ADVANCED TECHNIQUES IN MECHATRONIC SYSTEMS

Abstract

Sever oscillations in modern industrial processes are completely undesirable. Also, controller tuning needs to tackle this issue. PI-PD and PD-PI are controllers within the second generation of the PID controller-family which is proposed to solve this issue with improved performance regarding the spike qualities associated with the conventional PID controller. This work has demonstrated that utilizing the PI-PD and PD-PI controllers are fit for tackling the issues of the profoundly oscillated third order process. The controllers are tuned by minimizing error based performance indices such as: ISE, IAE, ITAE, ITSE, and ISTSE of the closed loop control system using the MATLAB optimization toolbox. The maximum percentage overshoot, and settling time are utilized to control the performance of the closed loop control system. The tuning of the used PI-PD and PD-PI controllers using the current tuning procedure is compared with a tuning technique based on using the minimum ITAE standard form.
