阐述无差拍控制旨在内环基于电流切实追踪输入电压形态,跟踪即滞后,电流滞后对比预测而言,实现交流协同,达成单位功率因数;其外环旨在基于取样输出输入电压有效值,予以对比,从而实施PWM功率流向操控,最终达成电压双向双馈操控;通过电力仿真软件PSIM搭建仿真,佐证基于无差拍控制机制的有效性。此外构建实验系统,论证无差拍控制算法的实用性和先进性。

This paper expounds that deadbeat control aims to effectively track the input voltage form based on the current in the inner loop.Tracking is lag.Compared with prediction,current lag can realize AC coordination and achieve unit power factor;The outer loop is designed to compare the effective value of the sampled output input voltage,so as to implement the PWM power flow control,and finally achieve the voltage bidirectional doubly fed control;Through the power simulation software PSIM.It is generally reliable to determine the operation of accurate shooting.Ultraviolet can determine its reliability and effectiveness.Ding took the experimental system at the party in recent years.
