Abstract: 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 ap?proach ，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 pro?vided 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.
