Design of High Stable PI Current Controller for Motor Driving System

摘要

This paper proposes a PI current controller to maximize stability of motor driving systems. The controller gains are determined by motor parameters with eliminating element of trial and error. We use Kharitonov equation to confirm the robustness of the controller with the change in motor parameters. The proposed controller is also able to provide a fast response, since the system poles are located at the same position. The effectiveness of the proposed controller is verified by simulation results.
