A Comparative Analysis of GA-PID, Fuzzy and PID for Water Bath System

Temperature is a very important parameter in industrial production. Recently, lots of researches have been investigated for the temperature control system based on various control strategies. This paper presents the comparison of GA-PID, fuzzy and PID for temperature control of water bath system. Different control schemes namely PID, PID tuning using Genetic Algorithms(GA-PID), and Fuzzy Logic Control, have been compared through experimental studies with respect to set-points regulation, influence of impulse noise and sum of absolute error. The new algorithm based on GA-PID improve the performance of the system. Also, it's fit for the complicated variable temperature control system. The simulation results show that the validity of the proposed strategy is more effective to control temperature.
