激光导向伺服系统中满意PID调节器的LMI设计

利用带有图像处理功能的小型激光导向伺服系统,可以大大降低目标坐标测定仪操作手跟踪动态飞行目标的操作难度,从而提高激光回波率.与经典的矩阵分解方法不同,本文以线性矩阵不等式方法,研究了激光导向伺服系统的满意PID调节器设计问题.首先从约束指标的相容性出发,给出满足与给定圆形极点约束相容的输出方差的取值范围.然后,在此取值范围内,得到了求取同时满足上述两种约束的PID调节器参数的方法.靶场试验结果证明了其有效性.

LMI DESIGN OF SATISFACTORY PID CONTROLLER IN A LASER ORIENTED SERVO SYSTEM

By means of a laser oriented servo system with the function of image processing, operational difficulties in the Target COMERO can be greatly reduced when an operator is tracking a dynamic flying target, and the laser echo ratio can be improved. As is different from the classical matrix decomposition approach, linear marix inequality method is used to solve the problem of design of satisfactory PID controllers in the laser oriented servo system. Beginning with the consistency of constraint indices, the range of the steady output variance, consistent with the constraint of circle poles, is presented. Then a method is provided to get parameters of PID controller when the constraint indices are consistent. Validity of the method is testified by results of the test in a proving ground.
