Problems solved by technology

[0004] When the vehicle-mounted mobile base photoelectric tracking turntable is working in the search state, it is required that the azimuth rotates at a high-speed angular velocity of 360° / s in the inertial space, and the pitch axis must always maintain the required inertial space angle; the turntable needs to be transferred from the high-speed search state to the tracking The stable time of the state is not more than 1s; the photoelectric tracking turntable usually performs tracking control according to the amount of image off-target, and the amount of image off-target due to the problems of long delay and large communication cycle, the conventional PID composite control with speed feedforward cannot guarantee High-precision tracking requirements for photoelectric turntables

Embodiment Construction

[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0053] like figure 1 As shown, a servo control system for a vehicle-mounted mobile base photoelectric search and tracking turntable, including a PC104 servo controller 1, an azimuth driver 2, an azimuth motor 3, an azimuth frame 4, an azimuth code disc 5, an azimuth fiber optic gyroscope 6, and a pitch driver 7 , pitch motor 8, pitch frame 9, pitch fiber optic gyroscope 10, pitch code disk 11, and inertial measurement system 12. The control system takes the PC104 servo controller 1 as the control core, and sends the generated voltage control signal to the azimuth driver 2 and pitch driver 7 through the DA interface unit 1a of the PC104 servo controller 1 . The azimuth driver 2 amplifies the power of the voltage control signal and drives the azimuth motor 3 to rotate, thereby driving the azimuth frame 4 to move, that is, driving the photoelect...

Abstract

The invention belongs to the field of photoelectric servo control and particularly discloses a servo control method for a vehicular moving-base photoelectric-search tracking turntable. The method includes the steps of inertial space search control for the photoelectric-search tracking turntable, namely acquiring motional new DA-port (digital / analog port) search voltage controlled volume of a control motor so as to allow a drive motor to drive the turntable to search; scram control for the photoelectric-search tracking turntable, namely acquiring motional DA-port scram voltage controlled volume of the control motor so as to allow the drive motor to drive the turntable to scram; and tracking control for the photoelectric-search tracking turntable, namely acquiring motional DA-port tracking voltage controlled volume of the control motor so as to allow the drive motor to drive the turntable to track. By the method, functional requirements of the moving-base photoelectric turntable for decoupling control can be met, the requirement of the turntable for high-precision tracking and positioning control can be met, and stable high-speed searching performance and search scramming and tracking performance of the turntable in inertial space can also be guaranteed.

Description

technical field [0001] The invention belongs to the field of photoelectric servo control, and in particular relates to a servo control method for a photoelectric search and tracking turntable of a vehicle-mounted moving base. Background technique [0002] The photoelectric tracking turntable is an important part of the photoelectric guidance and tracking equipment.
