Title: Tuning of a PI-PD Controller used with a Highly Oscillating Second-Order Process
Abstract: High oscillation in industrial processes is something undesired and controller tuning has to solve this problems. PI-PD is a controller type of the PID-family which is suggested to overcome this problem with improved performance regarding the spike characteristics associated with certain types of controllers. This research work has proven that using the PI-PD is capable of solving the dynamic problems of highly oscillating processes. A second order process of 85.45 % maximum overshoot and 6 seconds settling time is controlled using a PI-PD controller (through simulation). The controller is tuned by minimizing the sum of square of error (ISE) of the control system using MATLAB. The MATLAB optimization toolbox is used assuming that the tuning problem is an unconstrained one. The result was cancelling completely the 85.45 % overshoot and producing a step time response without any overshoot and undershoot. The settling time is reduced to only 0.35 seconds. The performance of the control system using an PI-PD controller using the present tuning technique is compared with that using the standard forms tuning technique.
