Fixed Set Point Weighting 2DOF PID Controller for Control Processes

Nowadays, many of control systems need a flexible controller in order to achieve the operation requirement precisely and rapidly to overcome nonlinearity, uncertainty, digital implementation challenges, and achieving at the same time both of control system objectives of load disturbance rejection and set point following. This paper is aimed to design and analysis one of the most common industrial controllers, set point weighting 2DOF PID controller, to get this target with simplicity and effectiveness. The paper included the main problem description, structure of the proposed controller, effectiveness of controller parameters variations, the methodology of effective tuning method, and an example of the proposed controller on control system platform. The results reveal the accurate and effective operational performance of the proposed controller to obtain the control system objectives.
