摘要

提出了一种基于微处理器鲁棒控制的并联多逆变器系统共流控制策略。采用平均分担电流控制(ACSC)策略，逆变器并联，每个逆变器都有电压鲁棒控制器来实现系统的稳定性和鲁棒性，电流鲁棒控制器来跟踪逆变器的平均电感电流以实现电流的均匀分布。单逆变器系统和双逆变器系统的仿真和硬件测量，以及线性和非线性负载下的三逆变器系统的仿真结果表明，所提出的控制方案在电流均匀分布和快速调节方面是可行的。

A current-sharing control strategy for paralleled multi-inverter systems using microprocessor-based robust control

A current-sharing control strategy for paralleled multi-inverter systems using microprocessor-based robust control is presented in this paper. With an averaged current-sharing control (ACSC) strategy, the inverters are in parallel connection and each inverter has a voltage robust controller to achieve system stability and robustness, and a current robust controller to track the averaged inductor current of the inverters to achieve an equal current distribution. Simulation results and hardware measurements of a single-inverter system and a two-inverter system, and simulation results of a three-inverter system with linear and nonlinear loads have demonstrated the feasibility of the proposed control scheme in equal current distribution and fast regulation.
