摘　　要：微电网稳定运行是可靠供电的有利保障,论文针对带有执行器故障、外部有限能量扰动的不确定孤岛交流微电网系统,提出鲁棒自适应H_(∞)补偿控制的设计方法。所设计的直接自适应状态反馈控制器既可补偿执行器故障和参数摄动的影响,同时也具有良好的扰动抑制能力。算例结果表明所提的控制方法可以有效解决不确定系统在出现执行器故障时,仍能使闭环故障系统一致稳定且具有一定的干扰抑制能力。The stable operation of micro-grid is a better guarantee of reliable power supply.This paper proposes a design method of robust fault-tolerant H_(∞) control with adaptive compensation for uncertain AC micro-grid system with actuator fault and external finite energy disturbance in island mode.The direct adaptive state feedback controller not only compensates with actuator fault and parameter perturbation,but also has good disturbance suppression ability.The numerical results show that the proposed control method can effectively solve the problem of uncertain system in the case of actuator failure,but still make the closed-loop fault system uniformly stability and have certain interference suppression ability.
