Abstract: The “LabMIMO” is an open-source, interactive, and user-friendly virtual learning workbench. This workbench is designed for nonlinear process control edification. This virtual laboratory offers the platform to comprehend and validate the essentials of a control system for the nonlinear coupled MIMO process. This paper presents the development details and impact of virtual labs on an engineering study. The process considered in the tool is unique and innovative Quadruple Conical Tank System (QCTS). The said system is developed and the mathematical model used in the tool is validated with actual physical laboratory setup. The LabMIMO consists the eight different experiments on open-loop and closed-loop system analysis for single-input single-output system and multi-input multi-output configurations of QCTS. It also covers the study on interaction and coupling effects for the nonlinear process. Diverse experimentations were intended to improve the knowledge on design and performance analyses of different classical and model-based control algorithms like MPC (Model Predictive Controller), Fuzzy Logic Controller (FLC), PID Controller. To ease E-learning, LabVIEW based a very accessible Graphical User Interface (GUI) developed. To address the very important requirement of virtual laboratory setup, the tool is made freelydownloadable in a license-free executable file version. Keywords : Virtual laboratory, MIMO Process Control, Nonlinear control, PID controller

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.

There are many processes with Multi-Input Multi-Output (MIMO), which are non-linear in behavior. A difficulty arises in designing of controller when system interacting between input-output variables and coupling effects. This paper discusses the performance investigation of the classical PI controller and fuzzy logic-based controllers for coupled nonlinear quadruple conical tank system (QCTS). Experimental comparative analysis of controller’s performance discussed in depth. The fuzzy logic approach is more suitable for the nonlinear system to have interactions and coupling effects.

Temperature is the most critical parameter to ensure the proper cleaning of beverage containers in bottle washer machine. The requirement and importance of temperature control of different treatment zones of bottle washer machine for small scale beverage industry has been discussed. The sample water heating tank has been considered as the treatment zone of the bottle washer machine. The temperature control of the sample water heating tank with VIPA 315-SB PLC using PID control has been discussed and implemented. Two tuning methods for PID control, namely Ziegler Nichols tuning and auto-tuning have been discussed and implemented. The novel approach for implementation of MPC using OPC server and MATLAB as an OPC client has been discussed and implemented for sample water heating tank system. The comparison between PID and MPC temperature control schemes have been shown in terms various performance indices. The results show that MPC provides better control and better performance compared to PID control scheme.

Different approaches of communication are available between the Mitsubishi FX-PLC and LabVIEW like OPC, Serial, etc. The communication between the PLC and personal computer (PC) is done using the Ethernet 1E. A MELSEC Communication (MC) protocol of Mitsubishi FX-series Programmable Logic Controller (PLC) is introduced and studied. LabVIEW is used as programming software. This communication has been implemented successfully in the supervisory system which is introduced in this paper. TCP/IP is used to establish the connection in the LabVIEW platform for the continuous sending and receiving of the data from the PLC.

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.

The conventional bottle washer machines are suitable only for medium scale and large scale beverage industry due to their high bottle washing capacity and mechanical and control complexity. This paper proposes the design and automation of the economical bottle washer machine for the small scale beverage industry without compromising its control capabilities. The importance and requirement of the bottle washer machine in the beverage industry has been discussed. The design of the proposed bottle washer machine for RGBs (Returnable Glass Bottles) has been created in the Creo software. The different treatment zones and working of the bottle washer machine has been discussed. The bottle washer machine has been automatized using the Siemens S7-317-2-PN/DP PLC (Programmable Logic Controller) and programmed using a ladder diagram in the SIMATIC Manager. The level control for different treatment zones is achieved by means of limit switches and temperature control for different treatment zones is achieved by using Pt1000 RTD, SSR (Solid State Relay) and heater. The different control schemes for the temperature control has been discussed, implemented and compared. The results show that the PID temperature control is the most effective control scheme for the temperature control of the different treatment zones. The implementation of the PID temperature control and auto-tuning of the sample process has been shown. The holistic control of the bottle washer machine also has been discussed and assessed.

This paper focuses on development of PID controller for a single tank level control system using concepts of industrial automation. The idea behind this work is to replace the conventional PID controller available in the level control trainer system with a high end Programmable Logic Controller. The motive behind doing this is to obtain a complete understanding of the changes in the dynamics of the system and transient response characteristics associated with the system. Mathematical model is obtained for the actual system using the mass-balance formulas and the same model is validated. Using NI-LabVIEW, a SCADA platform is developed to monitor the system and log the real-time process data. MODBUS RTU communication protocol is used to exchange the real-time process parameters between PLC and NI-LabVIEW. The developed setup can be used to analyze and implement advance process control algorithm like Auto tuning etc. in place of the existing conventional controller in future.

Drying is one of the complex and highly energy-consuming process unit operation used in many industry such as textile, paper, chemical, pharmaceuticals, agro and food-processing, sugar, etc. Significant R&D efforts are underway in last more than a decade to enhance dryer technology and operations to enhance its energy efficiency. A mathematical modelling and simulation framework is developed on the MATLAB-SIMULINK platform for rotary dryer. The model is semi-empirical based on the first principles using mass balance and moisture balance equations amongst the vegetables and hot air. Later, a mathematical model for textile dryer machine has been developed by modifying the rotary dryer model.
