Abstract

This research proposed a new tuning technique to search efficiently Proportional Integral Derivative (PID) parameters, by locating near-optimal tuning solutions, which compensate for delay time. The purpose is that to minimize response time by optimized PID gains Kp, Ki, Kd within a deferent order model. Related to survey, numerous existing papers propose to optimize proportional gains by introducing various methods. Most of these works cannot achieve to find the best solution for optimization of different orders system. By using both proposed tuning with improved selective switching, it is possible to obtain a maximum optimization for any order system. Proposed tuning was applied by using 17 steps with less than 39 generation loops; each generation includes four loops calculation. Response time is measured and compared with previous times until reached to optimal gains, then fixed Kp,Ki,Kd. The results show decreasing rise time to 0.0165s in the second order, and 0.119s in the third order with zero overshoot. Results prove that this method leads to more precise, effective, robust, optimization with less iteration and applicable to various plants. Furthermore, it is a quick, simple, powerful and more practical methodology, compared with PID toolbox tune.
