摘要
为了获得具有带宽高、动态响应快、输出电压谐波少、适应非线性负载强等特点的高性能单相逆变器,设计了带观测器的单相逆变器数字电压外环电流内环控制器,通过MATLAB仿真,结果表明该控制系统具有良好的稳态和动态特性,且在带非线性负载时总谐波失真非常小,从而得出基于观测器的数字电压外环电流内环控制器可以设计出高性能的单相逆变器。
In order to obtain a high bandwidth,fast dynamic response,low output voltage harmonics,to adapt to the characteristics of strong non-linear load,high-performance single-phase inverter,designed with observer digital single-phase voltage inverter current in the outer ring loop controller,through the MATLAB simulation results show that the control system has good steady and dynamic characteristics,and in the non-linear loads with total harmonic distortion is very small to arrive at the number of observer-based voltage current in the outer ring loop controller can design high-performance single-phase inverter.
