For a system with deterministic models of control objects such as power electronic converters and electric motors, a system model-based composite control strategy is proposed by combing a full state feedback (FSF) controller and ageneralized integrator (GI). First, compared with the proportional-integral-derivative (PID) and proportional-resonant (PR) controllers, this strategy canfully take advantage of the knowledge and information about the system model, so as to simplify the controller design and improve the system’s control performance. Then, based on the system-based model including the control object, the combination of a reference/disturbance model and an FSF closed-loop system model provides a simple and universal design approach for the composite control without the need for time-consuming trial and error. Finally, the proposed composite control strategy was applied to a 3 kVA three-phase PWM inverter, and results verified the feasibility of this strategy.
