Abstract
For control plants with an explicit model such as DC-DC converters, a system model-based control strategy which is an optimal composite of the plant model-based full state feedback (FSF) controller and the DC signal model-based integrator (I) is proposed. The proposed method can greatly simplify the control system design and significantly improve the control performance of the DC-DC converter systems. A simple universal design approach of the control strategy has been developed to synthesize the proposed FSF-I optimal composite controller. Compared with the plant model-free controllers such as PI and PID controllers, the FSF-I optimal composite controller is easier to design and tune, and also can achieve higher tracking accuracy, faster response, and better robustness. An application example of a 1 kW DC-DC converter is provided to verify the effectiveness of the proposed control strategy.
