Abstract: This paper recommends to employ differential (DE) evolution algorithm for obtaining the optimum tuning parameters of PID controller, three tank level process. Optimal tuning improves the performance of the process in terms of time domain specifications. DE based PID controller is simulated using MATLAB/Simulink software. To fix the initial ranges of PID parameters in DE, PID controller is designed initially for this process. The responses of PID and DE based PID controller are compared and it is evident from the simulation results that the proposed controller outcompetes over conventional PID.
