A Model-Based Predictive Current Controller for PWM Rectifier

摘要：

Model-based predictive current control scheme proposed in the paper is a constant frequency unipolar PWM control algorithm that achieves a sysmetrical zero-centered current error in every switching cycle. This method is intended to choose the suitable switching instants based on assumed values for the circuit model parameters rather than the real-time measurement of the actual parameters,no feedback is necessary for this control scheme. Based on the pre-determined circuit model of the three-phase PWM rectifier bridge, the desired switching instants are continuously generated so that the supply current is regulated to follow its current reference precisely. The results of simulation verify suggested scheme.
