摘要

针对级联h桥多电平逆变器(CHMI)，提出了一种基于互连和阻尼分配的无源控制器(IDA-PBC)。本文的主要目的是研究低谐波失真的输出电压波形调节。通过平均建模，将电路建模为端口控制哈密顿(PCH)系统。IDA-PBC具有在各种负载条件下调节电压的能力。将所提出的控制方案与传统的双环PI控制器进行了比较，并利用MATLAB-Simulink软件进行了详细的仿真分析。仿真结果表明，该算法在保持低谐波失真的同时，保证了系统在负荷变化过程中的快速响应时间和稳定性。

Interconnection and damping assignment passivity-based controller for cascaded H-bridge multilevel inverter

This paper presents an interconnection and damping assignment passivity-based controller (IDA-PBC) for Cascaded H-bridge Multilevel Inverter (CHMI). The main objective of this paper is to investigate the output voltage waveform regulation with low harmonic distortion. The circuit is modeled as a port-controlled Hamiltonian (PCH) system through average modeling. IDA-PBC is capable to regulate the voltage during various loading condition. The proposed control scheme is compared to the conventional double-loop PI controller and verified by detailed simulation analysis using MATLAB-Simulink software. Simulation results show that the proposed algorithm ensures fast response time and stability of the system during load change while maintaining low harmonic distortion.
