Problems solved by technology

[0004] In order to realize the high-precision and stable tracking control of the two-axis four-frame photoelectric pod, it is necessary to ensure that the inner azimuth frame and the inner pitch frame of the two-axis four-frame pod are always perpendicular to each other. The servo control technology of the two-axis four-frame photoelectric pod needs to solve the pod The problem of the linkage between the inner and outer frames, so its control technology is far more complicated than that of the two-axis two-frame photoelectric pod

Embodiment Construction

[0093] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0094] A servo control method for a two-axis four-frame airborne photoelectric pod. The photoelectric pod is composed of two axis systems, an azimuth axis and a pitch axis. The azimuth axis includes an inner azimuth frame and an outer azimuth frame, and the pitch axis includes an inner pitch frame and an outer frame. Pitching frame; the photoelectric pod passes through such as figure 2 , 3 The following methods are shown to achieve high-precision and high-stability photoelectric tracking control:

[0095] (1) The inner frame executes the designed inner frame position loop tracking control algorithm to obtain the inner frame speed loop control amount, and substitutes the speed loop control amount into the gyro speed loop stabilization loop to obtain the corresponding DA port voltage control amount, and the D...

Abstract

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.

Description

technical field [0001] The invention belongs to the servo control technology of an airborne photoelectric pod, and in particular relates to a platform stabilization technology and a high-precision photoelectric tracking control technology of a two-axis and four-frame photoelectric pod. Background technique [0002] The high-precision airborne photoelectric pod has the function of isolating the movement of the carrier and carrying the photoelectric load. Its main function is to realize high-precision and high-stability photoelectric tracking control under conditions such as carrier aircraft body vibration and external wind interference. With the enhancement of target maneuverability and the increase of user's functional requirements, the airborne electro-optical pod needs to have higher tracking ability, better platform stability ability and larger range of motion. [0003] As a structural form of the pod, the two-axis four-frame photoelectric pod can make the photoelectric p...
