Control system of vehicle-mounted pick-up stable platform

Abstract

The invention relates to a control system of a vehicle-mounted pick-up stable platform. A gyro, a potentiometer and a motor are installed on the vehicle-mounted pick-up stable platform and respectively used for sensing the angular speed of the platform, measuring the angle of the platform and driving the platform to rotate. The control system of the vehicle-mounted pick-up stable platform comprises a signal processing module, a power module, a stability controller, a locking controller and two feed-forward controllers; the stability controller, the power module, the motor and the gyro on the platform as well as the signal processing module form a stable loop of the system; the locking controller, the stable loop, the motor and the potentiometer on the platform as well as the signal processing module form a locking loop of the system; and the system can effectively isolate the interference caused by vehicle-mounted angular movement, inhabit the drift caused by the gyro, and improve thedynamic performance of the system.

Description

technical field [0001] The invention relates to a control system for a vehicle-mounted camera stabilization platform, which is suitable for the field of vehicle-mounted and track-based film and television shooting, and can be expanded and applied to fields such as ground investigation, radar stabilization, and tank artillery stabilization according to user needs, and can be applied to customs, frontier anti-smuggling, evidence collection, etc. Mobile command video acquisition, etc. Background technique [0002] Vehicle and track condition film and television shooting can effectively isolate the angular motion interference caused by the moving carrier to the payload, and at the same time realize the tracking and locking of the observation target. In order to ensure boresight stability, the gyro-stabilized platform control system must simultaneously solve the problems of isolating carrier disturbance and servo tracking. [0003] In order to solve the problem of isolating carr...

AI Technical Summary

Problems solved by technology

For a stabilized platform that uses a compound loop such as a locked loop, the external input signal will cause the response of the locked loop, which may produce an adjustment effect that lasts for several minutes, making it difficult for the camera to point to a given target and affect the control performance of the stabilized platform. no good solution

[0005] The tracking amount is generally called the torque-adding command, and the existing torque-adding command is generally given by a control interface such as a computer, and the operability is not good

The operator needs to constantly adjust the angle of the camera stabilization platform according to the movement state of the target to keep the moving target in the field of view. Tracking the same target for a long time will greatly increase the workload of the operator and is not conducive to the stability of the image
