Servo control method and system of two-axis four-frame optoelectronic pod

The invention belongs to the servo control technique of an airborne optoelectronic pod, particularly relates to a platform stabilizing technique and a high-precision optoelectronic tracking control technique of a two-axis four-frame optoelectronic pod, and provides a servo control method and system of the two-axis four-frame optoelectronic pod. The inner-outer frame linkage platform stabilization control technique is designed firstly to enable the pod to have good platform stability, the platform stabilization control technique can guarantee that an inner direction frame and an inner pitching frame to be perpendicular to each other constantly, geometry restraining coupling of the pot frames is reduced, and the optoelectronic pod is enabled to have good platform stability during zenith pass; on the basis, the inner-outer frame linkage optoelectronic tracking control technique is designed as well, and finally high-precision and high-stability optoelectronic tracking control of the optoelectronic pod is realized. The method and system serving as the key servo control technique applicable to the two-axis four-frame optoelectronic pod has good application prospect and brings high economic benefits and military benefits.
