【摘要】 针对具有匹配和不匹配干扰的三相逆变器系统，兼顾优化性能和节约成本的需求，提出一种基于误差符号积分鲁棒（robust integral of the sign of the error,RISE）方法的输出反馈控制策略。首先，建立系统误差动态模型，将不匹配干扰和匹配干扰转换为等效集总干扰，在此基础上进行控制器设计；其次，为估计不可测量状态信号，构建具有抗扰性能的鲁棒状态观测器；然后，在控制律中加入前馈补偿项和积分鲁棒项，以提高电压跟踪精度和处理等效集总干扰；最后，Lyapunov稳定性分析表明，闭环系统的观测误差和跟踪误差渐近收敛，仿真结果则进一步验证了论文所提策略的可行性和有效性。更多还原

【Abstract】 An output feedback controller based on the robust integral of the sgn of the error(RISE)method is proposed for the three-phase inverter with matched and unmatched disturbances,where the needs of performance optimization and cost reduction are taken into account. Firstly,the matched and unmatched disturbances are converted into equivalent lumped disturbances by establishing the system error dynamic model,on this basis,the controller is designed. Secondly,a robust state observer with anti-disturbance performance is constructed to estimate the measured state signal. Thirdly,a feedforward compensation term is integrated to improve the voltage tracking precision and an integral robust term is employed to handle lumped disturbances. Finally,the asymptotic convergence of observational error and tracking error are derived according to Lyapunov stability analysis,furtherly,the feasibility and effectiveness of the proposed strategy are demonstrated by simulation results.更多还原
