Simplified Fuzzy Logic Controller Design for Higher Order Processes

Ahmed I. Mohamed

Abstract: Several industrial processes are getting complicated day by day introducing an unstable higher order models. The proportional integral derivative (PID) controller is the most widely used control strategy in industry due to their robust performance in a wide range of operating conditions & their simple tuning methods. This paper presents design of PID controller using Ziegler-Nichols (ZN) tuning technique for controlling the higher order system. For the same purpose, A Fuzzy logic controller (FLC) using smaller rule set is proposed. Simulation results are demonstrated using MATLAB. Performance analysis shows the effectiveness of the designed Fuzzy logic controller as compared to the ZN tuned PID controller
