Servo Control System Design Of The High Performance Coordinator

With the rapid development of modern high-tech equipment, put forward higher request to the missile guidance technology. Seeker is the component of precision guided weapon, used to complete the target reservation, automatic search, recognition and tracking. Coordinator is the important part in the realization of seeker antenna in the execution device, is stable and target tracking, its performance directly affects the accuracy of Guidance Seeker.The coordinator as complex mechatronic device, the performance of the overall performance not only depends on the servo mechanism to further improve, but also from the design of servo control system.. In the paper, the high performance of the seeker servo control design point of view, analysis of the seeker servo control method, the semi physical simulation platform for the application of dSPACE semi physical simulation experiment to complete the sweep frequency analysis and control algorithm of servo mechanism, according to the characteristic of the control object of the servo mechanism, the introduction of dual speed loop control to reduce the friction of servo mechanism, eliminate some nonlinear factors, and the application of disturbance observer (DOB) to reduce the influence of dead zone on performance.
