| 摘 要： | 针对三相电压型PWM整流器这个离散的、耦合的、非线性的动态系统,引入开关周期平均算子将离散的系统变换为连续的系统,应用小信号扰动法将非线性的系统化解为线性的系统,进而分析系统的小信号动态数学模型。以TMS320F2812为控制器组建了三相电压型PWM整流器双闭环自动控制系统。实验结果表明了该系统具有良好的静态、动态性能,验证了数学模型的合理性。

| Abstract: | For the dynamic system of discrete coupled and nonlinear three phase voltage source PWM rectifier, the cycle switch average operator is introduced to transform the discrete system into continuous and the small signal perturbation method is used to transform the nonlinear system into linear, the small signal dynamic mathematical models are set up. The two closed loop automation system of three-phase voltage source PWM rectifier is built with the controller of TMS320F2812. Experiment results show the system h... |
