Performance Comparison of MPC and PID Controller for Single Input Single Output Process

Abstract

A controller is the heart of the automatically controlled processes systems. This paper discusses and compares between the different closed-loop controllers IMC based PID controller, Ziegler Nichols based PID and Model Predictive Controller. The major perspective of this paper is to find the optimal controller for the process (i.e) reach the steady state in fewer control moves and produce the less error. To analyse the performance of the system by designing various controllers for the process, Transient and Steady-state responses are used to evaluate the system in time domain. Transient response is determined by rise time, peak time, peak overshoot and settling time. Steady state response is analysed by Integral Square Error (ISE) and Integral Absolute Error (IAE).
