Fractional Controller Optimization for Liquid Level System Using MATLAB

Abstract

Conventional PID controller is oldest and one of the most widely used controllers in industry. In industrial development, the systems became more complex which leads to the requirement for more advanced controller. In this paper, the optimization technique for designing Fractional Order Fuzzy PI (FOFPI) controller is proposed. Controller designing is based on required values of peak overshoot and rise time. Optimal FOFPI gives better performance than PID, fuzzy logic PI and fractional order PI controller. FOFPI makes the system more robust.
