摘要研究了一种用于电压型PWM整流器的无差拍预测直接功率控制方法。该方法根据无差拍功率预测模型,在每一个采样周期,实现对下一个周期开始时的功率给定值的跟踪控制。采用空间矢量脉宽调制方法调制目标电压矢量,实现了直接功率控制开关频率的恒定。并在系统中引入了基于内模原理的准积分反馈校正环节,在每个采样周期对系统有功功率和无功功率的预测给定值进行修正。仿真表明,该方法有功功率、无功功率响应迅速、平滑,而且没有静差;控制器对系统参数变化不敏感,系统鲁棒性好,控制器设计简单,具有工程应用前景。

Abstract：In this paper, deadbeat predictive direct power control(P-DPC) is applied to voltage source pulse-width-modulation(PWM) rectifier. Based on the model of deadbeat power prediction, the method achieves the tracking control to the given power of the next cycle at each sampling period. It uses space vector pulse width modulation(SVPWM) to realize the objective voltage vector, which makes switching frequency of the direct power control constant. An internal model based feedback compensation link is introduced in the system to modify given predictive value of active power and reactive power in each sampling period. Simulation results show that this method has a rapid and smooth power response without steady-state error. The controller is not sensitive to system parameters change, achieving robustness of the system. And the controller design is simple to have a practical prospects.

Key words： Deadbeat predictive direct power control space vector pulse width modulation internal model feedback compensation
