摘　　要：针对二维扫描反射镜控制时可能遇到的脉冲干扰问题,以及设备制造时误差带来的参数不确定性,结合鲁棒脉冲-峰值理论提出了一种计算脉冲响应保守界,并设计了一个状态反馈控制器。通过理论建模得到二维扫描反射镜方位电机伺服控制模型,引入参数不确定性后,对该模型采用LMI优化求得控制器参数及峰值响应保守界。经过仿真验证,该方法相对于普通的PID控制方法减少了20%的峰值响应和50%的恢复时间,对于二维扫描反射镜脉冲干扰具有较好的抑制效果。The control of two-dimensional scanning mirror may encounter the problem of pulse interference and the parameter uncertainty caused by the equipment manufacturing error.A method for calculating the conservative bound of impulse response and designing a state feedback controller is proposed based on the robust pulse-peak theory.The parameter uncertainty should be considered when modeling the azimuth motor servo control system of two-dimensional scanning mirror.After LMI optimization,the conservative boundary of controller parameters and peak response is obtained.The simulation results show that the proposed method reduces the peak response by 20%and the recovery time by 50%compared with the conventional PID control method,and has a good suppression effect on the pulse interference of the twodimensional scanning mirror.
