    摘 要：傳統(tǒng)被動(dòng)式控制技術(shù)因輸入中電壓環(huán)路的缺失而導(dǎo)致負(fù)載輸出存在穩(wěn)態(tài)誤差，提出了一種改進(jìn)的被動(dòng)式三相多電平逆變器控制技術(shù)。該方法是根據(jù)能量整形和阻尼注入完成的，目的是將逆變器的能量流調(diào)節(jié)到最優(yōu)水平并保證全局漸近穩(wěn)定性，給出了多電平電壓源型逆變器的拓?fù)浣Y(jié)構(gòu)和數(shù)學(xué)模型；根據(jù)能量函數(shù)進(jìn)行能量整形和阻尼注入得到多電平 VSI 的開(kāi)關(guān)函數(shù)來(lái)確保系統(tǒng)的穩(wěn)定運(yùn)行；為消除負(fù)載的穩(wěn)態(tài)誤差將電壓回路引入開(kāi)關(guān)函數(shù)進(jìn)行線性規(guī)劃分析。通過(guò) MATLAB/Simulink 仿真，仿真結(jié)果表明系統(tǒng)在任何負(fù)載的情況下都具有良好的瞬態(tài)響應(yīng)和穩(wěn)態(tài)誤差，并且其 THD 值較低。

    Abstract: The traditional passive control technology has a steady-state error in the load output due to the lack of a voltage loop in the input. This paper proposed an improved passive three-phase multilevel inverter control technology.This method is based on energy shaping and damping injection. The purpose is to adjust the energy flow of the inverter to the optimal level and ensure global asymptotic stability.It provided the topological structure and mathematical model of the multilevel voltage source inverter. It performed the energy shaping and damping injection according to the energy function and obtained the switching function of the multilevel VSI. In this way, it could ensure the stable operation of the system. This study also introduced the voltage loop into the switching function for linear programming analysis,eliminating the steady-state error of the load.The MATLAB/Simulink simulation experiment results show that the system has a good transient response and steady-state error under any load, and its THD value is low.
    Key words: voltage source inverter; passive control; switching function; steady-state error; transient response
