摘要
分析了影响５０Ｈｚ ＳＰＷＭ 逆变电源输出电压特性的因素；针对其输出电压控制特性中存在的由于滤波网络导致反馈信号延迟大，进而引起电压超调量大、调节时间长等问题，提出了一种在反馈通道中加入特殊变结构控制的方法，将死区非线性控制与微分加相角超前网络结合起来，以解决电压控制中动、静态特性问题．实验证明该方法是非常有效的．
The causes influencing on the voltage characteristics of 50Hz inverters are analyzed. A special variable structure control method is proposed which is used in the feedback passageway and combines the dead zone nonlinear control with the differential plus phase lead network to solve the problems of the dynamic and steady state characteristics in the output voltage average value control. The method is verified to be effectual by experimental results.
