Repetitive Learning Control of Inverter System and Its DSP+FPGA Implementation

研究逆变电源系统的控制方法,就是要保证逆变电源系统在任何负载下,都能输出稳定、畸变小的电压波形,尤其是在带非线性负载环境中。针对逆变电源系统,采用重复学习控制方法,并在一台DSP+FPGA实现的逆变电源装置上进行实验论证。该控制方法通过跟踪误差来进行学习控制,可以有效改善逆变电源在任何负载下的输出波形。实验表明该方法具有高稳定性,快速跟踪和稳态误差小等特点。

The purpose of a voltage controller for inverter is to produce stable and regulated output voltage with low distortion under all loading conditions, especially under nonlinear loads. Based on inverter system, an iterative learning control method is suggested which tracks the errors in output voltage, and the experiment on a inverter based on DSP and FPGA is implemented. The method can improve the output voltage quality with high stabilization and fast response under nonlinear loads.
