Development and Application of Advanced Control Strategies for Nonlinear Coupled MIMO Systems Alpesh Patel, Dipak Adhyaru, Jignesh Patel Serbian Journal of Electrical Engineering, 2025 This paper presents the design and implementation of advanced control algorithms for a nonlinear coupled Multi-Input Multi-Output (MIMO) system, focusing on the hardware structure of Quadruple Conical Tank System (QCTS). Nonlinear MIMO systems, characterized by complex interactions between multiple inputs and outputs, pose significant challenges for control engineering. The QCTS, with its four interconnected conical tanks, serves as an exemplary testbed for evaluating advanced control strategies. The paper elaborates on the theoretical and practical implementation of Proportional-Integral-Derivative (PID) control, Fuzzy Logic Control (FLC), and Model Predictive Control (MPC), emphasizing their capabilities in managing multi-variable systems with constraints. Additionally, a comparative analysis of MPC with traditional control methods such as PID and FLC is presented. The practical implementation is demonstrated through hardware experiments. The hardware experimental results highlight the strengths and limitations of each control strategy, providing insights into their applicability for complex nonlinear MIMO systems. The findings underscore the superior performance of MPC in handling multi-variable interactions and constraints, making it a robust choice for advanced control applications in industrial processes.

Dry waste segregation using seamless integration of deep learning and industrial machine vision Harsh Kapadia, Alpesh Patel, Jignesh Patel, Shivam Patidar, Yash Richhriya, Darpan Trivedi, Priyank Patel, Meet Mehta Proceedings of Conecct 2021 7th IEEE International Conference on Electronics Computing and Communication Technologies, 2021 Municipal solid waste management has been one of the most critical issues of urban cities today. Increasing population, constructions, industries, etc. are the major factors creating a large amount of waste that is dumped onto the landfill sites. Various systems have been proposed and are under the utilization for the management of municipal waste which includes mechanical vibration-based size-based sorters, eddy current sensor-based sorting of metallic waste, automatic optical waste sorters, etc. This paper focuses on a novel solution for solid waste segregation using the concepts of machine vision and deep learning. The proposed concept is tested for the segregation of solid dry waste particularly plastic bottles, aluminum cans, and tetra packs. The prototype system developed for the segregations works at high speed and accuracy. The prototype system sorts 250 objects per minute with an average accuracy of 96%. The proposed novel idea be extended and implemented for other types of waste segregation and can include more categories of solid dry waste. The system provides a solution for the ever-challenging municipal waste management problem.
Comparative studies of control performance for a nonlinear coupled quadruple conical tank system Alpesh Patel, Jignesh Patel, Bhavik Patel 2019 6th Indian Control Conference Icc 2019 Proceedings, 2019 There are many processes with Multi-Input Multi-Output (MIMO), which are non-linear in behavior.

SBHS: Some control investigations Priyabrata Majhi, Harsh K Kapadia, Alpesh I Patel, Jayesh J Barve, Divyesh R Raninga Nuicone 2015 5th Nirma University International Conference on Engineering, 2016 The main motive of this paper is to implement, analyze and compare few standard closed loops PID tuning methods and to develop auto tuning for single board heater system (SBHS) using relay feedback method. For system identification, step test method is used to find out system parameters. Widely accepted PID controller is used to control the temperature of the system with the PID controller parameter values obtained from Zeigler Nichol's tuning method. Better to this conventional ZN, Relay Feedback tuning based PID controller is used, whose main idea was proposed by Amstrom-Hagglund in 1984. This paper also includes implementation of LQR(linear quadratic regulator) controller over linear system i.e. SBHS to reject disturbances with set point tracking, number of analysis and results has been taken for both LQR and PID controller.
