Active disturbance rejection servo system forvehicle photoelectric stabilization and tracking platform

Aiming at the disturbance characteristics of vehicle photoelectric stabilization platform and the separation characteristics of active disturbance rejection control(ADRC) algorithm, an active disturbance rejection control system was provided with integral compensation for improving the servo performance of vehicle photoelectricity stabilization tracking system. Practice swing testing shows that the ADRC method ensures the stabilization precision of platform is 0.129 mil（1）, and improves the automatic tracking performance. It is an excellent controller for stabilization platform tracking circuits.
