Abstract: In this paper proposes an intelligent approach (Fuzzy logic) for the design of PID controller for better disturbance rejection. The proposed PID controller is designed using pessen’s tuning algorithm for rejection of different disturbances. The proposed intelligent controller has got so many advantages/features over the conventional methods. Sudden ability to reject non linear disturbances arch occur in the system during operation ,speed of operation and PID gains are altered online in accordance with the disturbances to reject. To show the efficacy of the proposed method a liquid control of process tank is considered and intelligent PID controller is designed .The designed intelligent controller is simulated under different disturbance using MATLAB/Simulink. The results are successfully verified.
