An Improved Predictive Control for Vienna Rectifiers with Current Tracking Error-based Disturbance Adaptation

The traditional predictive current control (PCC) for Vienna rectifiers is sensitive against the mismatch of filter parameters. In this research, an optimized PCC is developed with a real-time disturbance estimation and compensation. Unlike the conventional methods, which calculate the disturbance by using an additional observer, the proposed method directly constructs the parameter mismatch related disturbance based on current tracking error. The developed method has the characteristics of good parameter robustness, concise structure, and fast dynamic response. Through the experiment and simulation tests, the effectiveness of this method is justified.
