Proportional-integral-derivative (PID) controller has been the most adopted controller applied in various industrial control applications due to its simplicity and its ability to provide a desired control response. However, conventional PID controllers tend to suffer from an integral windup that can cause oscillations or overshoot in the system output, degrading the controller performance. Besides, it also experiences tuning difficulty for an optimum control performance due to its highly coupled tuning gains. This study proposed an anti-windup controller with a semi-decoupled tuning gains design. The implementation of the semi-decoupled tuning gains aims to ameliorate the dynamic performance of a PI controller. The performance of the proposed controller was compared with the conventional PI controller and the steadystate integral PI controller. The proposed controller showed a faster response with a minimal overshoot in the motor speed control hardware simulation under no-load and loading conditions.
