摘要
文章分析了PWM逆变器模拟控制的特点,采用了一种PI双环(输出电压外环电容电流内环)模拟控制方案,利用极点配王的方法设计控制系统参数,通过仿真分析了该控制方案的可行性,最后给出了各种条件下的实验波形。实验结果表明该方案设计简单、实用,能很好地达到逆变器输出的各项性能指标要求。
The characteristic of analog control of PWM inverters is analyzed and an analog control scheme of PI dualloop is applied. The parameters of control system are designed by the method of pole assignment. Simulation analysis demonstrated the feasibility. At last, the experiment waveforms were presented. The experimental results demonstrated that the design process of this scheme was easy and the system could achieve good dynamic and static performance.
