Robust Controller Design of a Single-Phase AC/DC PWM Converter

摘要：

This paper proposes a robust digital controller for a single phase PWM converter. The proposed controller is based on a characteristic ratio assignment (CRA) method which has the ability to deal with the overshoot and response speed of an all-pole system directly. The error-space feedback control scheme to carry out the robust AC current tracking is used which is well known as an analytic state-feedback method to give a controller the ability to track a non-decaying input perfectly and to reject a non-decaying disturbance such as a sinusoidal input firstly. And then, the CRA design formulates a model matching problem whose reference model is selected from a target polynomial. So the state feedback gains can be determined by the CRA method instead of the pole-placement method. Finally, the validity of the proposed control technique is verified through the PSiM simulation and experimental results.
