Summary:根据端口受控耗散哈密顿(PCHD)系统模型方程,建立了 PWM 整流器在同步旋转 dq 坐标系中的 PCHD 数学模型。采用IDA-PB 控制思想,利用注入新的阻尼耗散项的作用及系统功率守恒原理,无需求解偏微分方程就可推导出 PWM 整流器的IDA-PB 控制规律。同时证明了 PWM 整流器的稳定性。根据所设计的控制规律对系统进行仿真和实验,实验结果表明采用注入阻尼耗散项的 IDA-PB 控制方法,系统具有良好的动、静态性能以及较强的鲁棒性。

This paper establishes PCHD model of PWM rectifier in synchronous dq coordinates based on the Port-Controlled Hamiltonian Damping model equation. Using IDA-PB control and the function of the new damping injection and the power conservation principle of the system, it's easy to deduce the IDA-PB control law of PWM rectifier without solving PDE. And the stability of PWM rectifier is proven. The validity of the IDA-PB control law is verified by simulation and experiment. The results show that using the IDA-PB control by damping injection, PWM rectifier has good steady and dynamic property, as well as strong robustness.
