Genetic Algorithm based I-P Controller for Superheated Steam Temperature Control System

In this paper, Integral Proportional (IP) controller is applied for the control of superheated steam temperature (SST) system. The Genetic Algorithm (GA) is used for the tuning of I-P controller. The performance investigation of GA based I-P controller is evaluated on superheated steam system of 500 MW boiler. The GA and conventional Zeigler-Nichols (ZN) method are employed for the tuning of I-P controller. The results obtained from GA and ZN based I-P controller are compared with GA and ZN based Proportional Integral (PI) controller. The results indicate that GA based PI and I-P controllers have better response than Z-N based PI and I-P controllers in respect of settling time, rise time and peak overshoot.
