| 摘 要： | 针对三相电压型PWM整流器的非线性特点,提出了一种混合控制方案.电流内环采用滑模控制,根据指数趋近律算法设计两个滑模电流控制器.电压外环采用负载电流前馈补偿和输出直流电压反馈控制的方法.采用空间矢量脉宽调制方法生成整流器的开关信号.仿真结果表明:系统不仅具有良好的动态和稳态性能,而且对负载及系统参数扰动具有很强的鲁棒性.

| Abstract: | According to the nonlinear characteristic of three phase voltage source PWM rectifiers,a hybrid control scheme was presented.Using sliding mode control method,the inner current control loop was set up.Two sliding mode current controllers were designed by exponential reaching law algorithm.The outer voltage control loop was based on load current feed-forward compensation and output DC voltage feedback control method.The rectifier switching signals were generated by space vector pulse width modulation method.... |
