摘　　要：在三相电压型PWM整流器传统模型预测直接功率控制(Model Predictive Direct Power Control,MPDPC)的基础上引入延时补偿控制,得到一种改进MPDPC。为了探究改进MPDPC和传统MPDPC的鲁棒性及其鲁棒性主要受哪些参数影响,文中通过计算改进MPDPC和传统MPDPC在不同功率下分别取不同大小的交流侧滤波电感、电阻时系统的功率偏差及交流侧电流畸变率。对计算结果进行分析,表明MPDPC的鲁棒性主要受滤波电感的影响,且改进MPDPC的鲁棒性优于传统MPDPC的鲁棒性。该研究结果对MPDPC系统参数的选取、提高系统的性能等有一定的参考价值。This paper proposed an improved model predictive direct power control （MPDPC） of three-phase voltage sourced PWM rectifiers that introducing delay compensation control based on conventional MPDPC. In order to study the robustness and its robustness is mainly influenced by which parameters of improved MPDPC and conventional MP- DPC, this paper calculated deviation of power and harmonic spectrum of grid current between improved MPDPC and traditional MPDPC under different load power with different filtering inductance, resistance, respectively. The analysis of the calculation results shows that the robustness of MPDPC is mainly affected by the filter inductance, and the ro- bustness of improved MPDPC is superior to traditional MPDPC. The study of MPDPC is good for selection of system parameters, and improving system performance, which has some reference value.
