重复控制在模型预测直接功率控制中的应用
Application of Repetitive Control to Model Predictive Direct Power Control
摘要
Abstract
To accurately track the power in model predictive direct power control(MPDPC),repetitive control is ap?plied to the model prediction of three-phase voltage source PWM rectifier.Under a two-phase static coordinate system and based on virtual flux orientation,the switching frequency is kept constant by the space vector pulse width modula?tion(SVPWM).Cost function is established by the minimization of the sum of squared errors between model predictive power and measured power,thus the optimal voltage vector can be chosen. The input signal in every control cycle is modified by error signal which is constantly accumulated and fed back by repetitive control,which helps the measured power value accurately track the power reference value,and achieve the goal of eliminating static error.The feasibility of the improved method is validated by simulation and experimental results.关键词
