(188e) Controller Design for CSTR Process Output Using a Combination of GA, PSO, Fuzzy and PID Algorithms for Quick Rejection of Process Disturbances
Efficient controller design is a vital component of chemical process design. The aim of the control system is to address any process upset as quickly as possible to maintain the process within the specified operating parameters. As such, fast response time for the controller is an important design criteria. One option for achieving this is to develop an adaptive controller that exhibits the lowest possible variable dependence.
In this work, a CSTR system output has been used to study and compare responses of controllers developed using GA-PID, GA-Fuzzy, and PSO-PID algorithms. The aim of this study is to evaluate which combination of algorithm is the quickest in rejecting disturbances in the system. In the case of GA-PID and PSO-PID, GA and PSO were used to determine best control weighting factor (ð) and rise-time parameter (ð). However, in the case of GA-Fuzzy, GA was used to determine the best applicable Fuzzy membership functions for the operating parameters obtained from literature.
