  • Energy Management System for a Multi-Source Electric Power System Architecture in More Electric Aircraft
    Aditi Karvekar, Sushil Karvekar
    Fuel Cells, 2025
    This research paper intends to present a detailed design of electric power system architecture of half‐ and full‐span of an aircraft and the energy management system in aircraft EPS to operate fuel cells, battery stacks, and supercapacitors at appropriate times. A fuel cell of appropriate power rating is used as APU for the AC bus in the aircraft in conjunction with a supercapacitor. A battery stack is connected to the DC bus through a bidirectional DC to DC converter which acts as APU for the low‐power high‐priority DC loads with faster dynamic response and caters to the power needs of these loads under emergency conditions. The battery keeps getting charged from fuel cell under normal operating conditions. The system response is analyzed over a flight cycle with randomly changing load under normal and emergency conditions. The research is intended to use the best qualities of fuel cells, battery stack, and supercapacitors for the role of the APU in an aircraft. All three of them at proper power ratings are implemented and an energy management system is developed to use fuel cell for major loads, supercapacitor for sudden load changes, and battery stacks for minor load changes.
  • Simulation Modeling for Comparative Analysis of SPWM and SVPWM in Solar PV Inverters
    Sushil Karvekar, Aditi Karvekar
    Proceedings 2025 4th International Conference on Computational Modelling Simulation and Optimization Iccmso 2025, 2025
    The performance of space vector pulse width modulation (SVPWM) and sinusoidal pulse width modulation (SPWM) techniques for solar photovoltaic (PV) inverters is compared in this study with an emphasis on power consumption, harmonic distortion, and efficiency. Using simulation and hardware implementation, the investigation shows that SVPWM performs better than SPWM. Improved DC bus voltage utilization, decreased overall harmonic distortion, and enhanced inverter efficiency with SVPWM are some of the main conclusions. Software simulations were used in the study, and their validity was confirmed by hardware implementation. A 125 kW rooftop solar PV system at Walchand College of Engineering, Sangli, was used to test and confirm the hardware results. SVPWM is recommended for highperformance solar PV systems because it can lower switching losses and increase system efficiency, while SPWM is still practical for low-power, cost-sensitive applications. The study comes to the conclusion that SVPWM-based control schemes can greatly improve the performance of solar PV inverters, especially in residential and commercial PV installations. This emphasizes how crucial advanced PWM techniques are to the optimization of renewable energy systems.
  • Implementation of AVR Systems with Comparative Analysis of PID Controller using Fuzzy Logic and PSO Algorithms
    Sushil Karvekar, Aditi Karvekar, Vijay Mohale
    5th IEEE International Conference on Sustainable Energy and Future Electric Transportation Sefet 2025, 2025
    Automatic Voltage Regulator (AVR) systems are essential for maintaining a steady voltage output in synchronous generators by adjusting excitation levels. However, due to system delays and high inductance in the generator’s field winding, voltage oscillations can persist, affecting system stability. This paper compares two control strategies—Fuzzy Logic Control (FLC) and a PID controller optimized using Particle Swarm Optimization (PSO)—to improve AVR performance. Fuzzy Logic Controllers rely on human-like reasoning, making them adaptable for complex systems without needing a precise mathematical model. In contrast, PID controllers are widely used for their stability and reliability but require proper tuning for optimal performance. The PSO algorithm is used to fine-tune the PID controller, ensuring faster response, better stability, and improved control accuracy. A Sliding Mode Controller is designed to control the AVR voltage under load variation conditions and the performance of the SMC is compared with those of Fuzzy PID and PSO PID. The real time transfer functions for AVR system components are taken from the data received from the AVR system deployed at Chandoli dam in Maharashtra. Simulations in MATLAB/Simulink and real-time testing on dSPACE 1104 demonstrate that the PSO-tuned PID controller significantly reduces oscillations and improves system performance compared to the fuzzy logic approach. However the SMC proves to be the best choice in terms of transient response parameters such as peak overshoot and settling time. The results confirm that Sliding Mode Control is more effective in maintaining stable voltage under varying load conditions, making it a superior choice for AVR systems.

    2022 2nd Asian Conference on Innovation in Technology Asiancon 2022, 2022
    The paper presents performance analysis of speed control techniques for Induction motor and BLDC motor using EPLL based field oriented control algorithm. EPLL is an adaptive notch filter used for parameter estimation and synchronizing the control signals in rotating reference frame. It improves the overall efficiency by reducing the computational burden during the estimation of parameters. The simulation for speed control of these ac motors is implemented using Matlab/Simulink and the results demonstrate the effectiveness of the proposed system. The hardware implementation of the speed control strategy for BLDC motor is presented using C2000 DSP microcontrollers and DRV8301 based inverter. The real-time implementation of control algorithm using DSP controller is discussed for speed control of BLDC motor.

    2022 2nd International Conference on Intelligent Technologies Conit 2022, 2022
    This paper presents, the speed control of three phase induction motor based on integral sliding mode controller (ISMC). By using vector control method, the decoupling effect has been achieved in between electromagnetic torque and field flux. In order to improve the high performance of an induction motor, the sliding control law in the form of integral sliding surface has been defined. The proposed integral sliding mode controller is compared with PI controller. The simulation and design analysis of the proposed model is demonstrated by using MATLAB/SIMULINK. The proposed work proves that integral sliding mode controller achieves better response than conventional PI controllers.
  • Implementation of EPLL based PWM Rectifier for Charging Station Using Co-simulation Approach
    Sushil Karvekar, Prasad Joshi
    Proceedings of the 2nd International Conference on Artificial Intelligence and Smart Energy Icais 2022, 2022
    Active rectifiers for charging batteries of Electric Vehicles can be used for voltage regulation and harmonics mitigation. This paper aims to implement PWM rectifier at Electric vehicle charging station for unity power factor operation. Enhanced Phase Locked Loop(EPLL) based reference current generation technique is implemented for control of PWM rectifier. The paper investigates the performance of the PWM rectifier by using co-simulation technique in PSIM and Matlab/Simulink environment. The control algorithm for reference current and pulse generation is developed on Matlab/Simulink software while the power circuit is implement using the PSIM software. The EPLL based reference current generation technique ensures constant DC link voltage required for the charging of electric vehicle. Moreover, the supply side harmonics are mitigated by the system thereby ensuring unity power factor and sinusoidal source current. The results obtained in PSIM and Matlab/Simulink prove the effectiveness of the proposed system.
  • SOC Control of Lithium-Ion Battery Using Fuzzy Logic Controller and PID Controller Employed in DC Micro Grid
    Priyanka Wagh, Sushil Karvekar
    2022 2nd International Conference on Intelligent Technologies Conit 2022, 2022
    Integrating solar panels in DC micro grid is a big task, since it involves a battery for power storage and battery controller. The most tedious task is enhancement of battery life and efficiency. This paper introduces two separate models of DC micro grid, one regulated by fuzzy logic controller and the other one by a conventional PID controller. The fuzzy logic controller is implemented in MATLAB Simulink based upon Mamdani inference system. MPPT, fuzzy logic controller, lithium-ion battery and DC load are all integrated in one Simulink model. Best possible rule base is developed to regulate power flow through the DC micro grid, thus simultaneously enhancing the performance of lithium-ion battery. The fuzzy logic controller facilitates maintenance of SOC of lithium-ion battery within desired limits, which results in prevention of overcharging and over discharging. Also, conventional PID controller is implemented in MATLAB Simulink for maintaining SOC of lithium-ion battery within desired limits. This model involves integration of PID controller, MPPT, bi-directional DC-DC converter and lithium-ion battery. Based upon the obtained performance and results of both Simulink models, a comparison between the two controllers is deduced and corresponding results are analyzed. Transient response analysis is performed to compare the two controllers.
  • Implementation and Performance Analysis of Speed Control Strategy for Induction Motor using a Novel PLL and Discrete Fourier Transform
    Sushil Karvekar, Prasad Joshi
    2022 IEEE 3rd Global Conference for Advancement in Technology Gcat 2022, 2022
    The paper presents implementation of speed control strategies for Induction motor using field oriented control and adaptive notch filters. The adaptive notch filters used for developing filed oriented control include EPLL and discrete Fourier transform. Co-simulation technique is employed by using Matlab/Simulink and PSIM softwares for implementing the speed control algorithm. The simulation results of these adaptive notch filters demonstrate the computation of torque and flux components in rotating reference frame. The practicability and reliability of these algorithms are validated by changing the reference speed and torque conditions. The simulation results demonstrate the performance of field oriented control algorithm using the discrete Fourier and EPLL for tracking the given reference speed. The results show that the modified control algorithm is efficient in reference tracking with improved computational efficiency.
