Abstract
AbstractLow‐pass filters are effective for noise reduction in control systems. This article treats an integral‐proportional derivative‐type PID (I‐PD) control system with low‐pass filter. First, we show a closed‐loop transfer function from reference value to the output of the system. The I‐PD controller is designed based on the pole placement method. Second, we introduce several conditions of the controller to be satisfied. Finally, we present that the proposed methods have obtained a good result by a simulation example and an experimental result of speed control for a DC motor.
