Abstract: In Industry nowadays the control of chemical process is important task. Mostly all the chemical processes are highly nonlinear in nature and this causes instability of process. Continuous Stirred Tank Reactor (CSTR) is an important subject in chemical process and offering a diverse range of researches in the area of the chemical and control engineering. In this paper the design of a nonlinear feedback controller is analyzed for temperature control of continuous stirred tank reactors (CSTR) which have strong nonlinearities. Here Particle Swarm Optimization (PSO) algorithm based PID controller tuning is attempted for the temperature control of Continuous Stirred tank reactor (CSTR), Based on the Performance indices and optimization criterion controller can be estimated. The Integral Square Error (ISE) criterion is used to guide PSO algorithm to search the controller parameters like Kp , Ki , Kd . A comprehensive simulation is carried out with PID and GA controller Structures. The simulation results show that the PSO based PID controller tuning approach provides better performance compared to other conventional PID tuning methods.
Keywords: PID controller, Particle Swarm Optimization Algorithm (PSO), Genetic algorithm (GA) Stochastic systems, CSTR.
