Comparative study of PID controller and sliding mode controller for the setpoint overshoot method

Abstract

This paper deals with the study of comparative study of PID controller for the overshoot of setpoint in tuning. The main objective of this paper is to compare time specification performance between conventional controller PID and sliding mode controller for setpoint overshoot in tuning. The goal is to determine which strategy deliver better performance with respect to time. The two controllers are presents such as Sliding Mode Control (SMC) and Proportional Integral Derivative (PID) controlling the setpoint response experiment and it mainly uses information about the first (overshoot) which is very easy to identify the setpoint experiment is similar to the classical Ziegler-Nichols experiment. Based on simulations for range of first order with delay process, simple correlations have been derived to give PI controller setting similar to those of SIMC tuning rules. And here we developed Modified Setpoint Overshoot Method i.e. MSOM by using SMC. The proposed tuning method , originally derived for first order with delay process, has been tested on wide range of other process typical for process control applications and results are comparable with SIMC tuning and MSOM tuning model. The effectiveness of proposed method is evaluated by simulations conducted on MATLAB/SIMULINK.
