电压型PWM整流器模型预测直接功率控制
Model Predictive Direct Power Control for Three-Phase Voltage Source PWM Rectifiers
摘要
Abstract
Mathematical modeling of voltage source PWM filter is conducted and a predictive power model under two-phase rest frame is established, on this basis an optimal model predictive direct power control (MPDPC) strategy is proposed. In the proposed control strategy the voltage vector in power supply system is taken as the basic control vector and utilizing power directive model and minimum power error principle the formula of objective control voltage vector is obtained, then combining with space vector PWM modulation(SVPWM) the model predictive direct power control is implemented. Meanwhile, considering the step delay in actual control systems a delay compensation scheme is designed. Besides, the repetitive control is led in to optimize the active and reactive power in each sampling cycle. The feasibility of the proposed control method is validated by results of simulation and experiments.关键词
