經(jīng)典PID控制算法在逆變器中獲得廣泛應(yīng)用，但控制效果和精度有待改進(jìn)和提高，針對(duì)此問(wèn)題，研究了雙環(huán)控制算法在逆變器控制中的應(yīng)用，給出了雙環(huán)控制逆變器的結(jié)構(gòu)，設(shè)計(jì)了電壓環(huán)和電流環(huán)的控制參數(shù)。在MATLAB/Simulink軟件中構(gòu)建了雙環(huán)控制逆變器的仿真模型，通過(guò)仿真，驗(yàn)證了控制參數(shù)選擇的可行性，證明逆變器在采用雙環(huán)控制算法時(shí)具有好的輸出性能。

　　Abstract:

　　The classical PID control algorithm is extensively used in inverter， but its control precision should be improved， Being aimed at this problem， double loop control algorithm in inverter’s control is researched in this paper. The composition of inverter using double loop control algorithm is given， and the parameters’ of voltage and current are designed. Simulation model of inverter by using double loop control algorithm is constructed .By the way of simulation， the choose of control parameters are tested and verified， and it’s proved that the inverter has good output performances when double loop control algorithm is used.
