Modeling Simulation and Control Of Large Time Delay Process

Abstract

In this proposed project it is to work toward modeling, simulation and control of process variable like temperature with large time delay. The project includes system identification and control of temperature system with variable time delay. A physical model will be developed which exhibits variable time delay. By running system in open loop System Identification will be carried out on platform like MATLAB. Next part is to develop PID controller for the temperature system without time delay on platforms like NI-LabVIEW. Then implementation of same PID controller settings on temperature system with time delay will be carried out. After successful implementation of PID controller on both systems comparative analysis will be done to check whether PID controller gives satisfactory results or not. The next step is to develop Smith Predictor in NI LabVIEW and simulation would be carried on each model and comparative analysis would be done. PLC (Beckhoff EK-1100) will be used as data acquisition i.e. it will acquire data from sensor and drive the actuator accordingly. Comparative analysis will be done between two controllers and depending upon the results conclusion would be drawn.
