Performance Comparison Of Different Controllers For A Level Process

摘要

The analysis study has been done for a First Order plus Delay Time (FOPDT) model controlled by Proportional Integral Derivative (PID), proportional integral (PI) and Model Predictive Control (MPC) using MATLAB software. The study has been done for both MPC and conventional control methods to design the controller for the level tank system and the results has been compared in terms of rise time,settling time and maximum overshoot. The conventional PID controller gives corrective action only after error has developed but not in advance but MPC provides corrective action in advance. The objective of this study is to investigate the Model predictive control (MPC) strategy, analyze and compare the control effects with conventional control strategy in maintaining a water level system. A Comparison between the performance of Conventional controller and MPC Controller has been performed in which MPC Controller gives better system parameter in terms of Rise time (tr), Settling time (ts) and maximum overshoot (Mp).
