摘要

目前从控制策略上研究五电平逆变器的研究较少。为此

将非线性的无源控制（PBC）理论应用于五电平逆变器的控制之中

该方法从能量成型的角度考虑控制系统的构造

且需要选取适当的能量函数与注入阻尼。首先根据五电平逆变器的拓扑结构及其开关函数推导出其数学模型;然后选取适当的能量函数与注入阻尼确定无源E-L模型控制器的开关函数

并将推导出的开关函数结合调制算法驱动并网系统。仿真和实验表明

相比于传统的PI控制

无源控制不但提高了系统的动、静态稳定性

还降低了逆变器输出电流谐波

提升了系统的经济性。

Abstract

At present

the five-level inverter from the control strategy is rarely studied. Therefore

we apply the nonlinear passivity-based control（PBC） theory to the control of five-level inverters.In this method

the structure of control system is considered from the viewpoint of energy forming

and the selection of anappropriate energy function and injection damping is needed. Firstly

a mathematical model is deduced according to the topology of the five-level inverter and its switching function. Then

the mathematical model of the five-level inverter is transformed into the passive Euler-Lagrange（E-L） expression by selecting the appropriate energy function and injection damping

and the switching function is combined with modulation algorithm to drive the grid-connected system.Simulation and hardware experiments show that

compared with the traditional PI control

the passivity-based control not only improves the dynamic and static stability of the system

but also reduces the output current harmonics of the inverter and improves the economy of the system.
