摘要：In this paper the design of a nonlinear feedback controller is analyzed for concentration control of continuous stirred tank reactors (CSTR) which have strong nonlinearities. Continuous Stirred Tank Reactor (CSTR) is one of the common reactors in chemical process and all industrial process requires a solution of specific chemical strength of chemicals considered for analysis. Here Particle Swarm Optimization (PSO) algorithm based PID controller tuning is attempted for the concentration control of Continuous Stirred tank reactor (CSTR). Based on the Performance indexes and 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 I-PD controller Structures. The simulation results shows that the PSO based PID controller tuning approach provides better performance compared to other conventional PID tuning methods
