Abstract
One of modified versions of the PID controller is the PI-PD controller. Generally, the PID controller is placed on the forward path causing the very higher control signal called the set-point kick effecting to the power electronic devices. This paper proposes the PI-PD controller which its P- and I-elements are placed on the forward path, where as its P- and D-elements are placed on the feedback path. In this work, the bat search (BS) is applied to design the PI-PD controller for temperature control of an electric kettle. Result of the PI-PD controller will be compared to those of the PID and I-PD controllers. As results, the BS can design the PID, I-PD and PI-PD optimally. The PI-PD produces small set-point kick than the PID does. Moreover, the PI-PD can provide the least overshoot and settling time and can reduce the set-point kick as the PID does.
