摘　　要：介绍了一种优化设计的鲁棒性控制技术,针对逆变系统中可能存在的不确定性,如滤波电感值,滤波电容值,通过状态反馈和整合跟踪错误,优化设计线性矩阵不等式(LMI),获得状态估计器最佳增益,使收敛速度最大化,在同步dq坐标系中加以描述,采用空间矢量调制技术实施。仿真结果和实验测试证明该优化控制方法具有良好的跟踪性能。An optimal design of robust control techniques is described for there may be uncertainty in the inverter system, such as filtering inductance, filter capacitance value. Through state feedback and integration tracking error, the design of linear matrix inequality （LMI） is optimized. In order to obtain optimal gain of the state estimator the speed of convergence is made maximum. It is described in synchronous dq coordinate system, using space vector modulation implemented. The simulation results and experimental tests show that the optimization of control method has good tracking performance.
