Problems solved by technology

For a stabilized platform that adopts a compound loop such as a locked loop, the manipulation control signal will cause the response of the locked loop, which may produce an after-effect of adjustment that lasts for several minutes, making it difficult for the camera to point to a given target, and affecting the control performance of the stabilized platform. no good solution
[0005] The tracking amount is generally called the torque-adding command, a

Abstract

The invention relates to a vehicle-mounted pick-up stable platform. The platform adopts a potentiometer as a feedback element of a locking loop, a motor is controlled to move through the angular speed of gyro sensitive vector disturbance, the interference of vector movement is isolated, the drift of a gyro is inhabited, and the stability of a relatively inertial space of a payload is realized; moment increase is carried out by the control unit by adopting a photoelectric encoder and is visual and easy to operate, and the moment increase is carried out by adopting feed-forward control, thereby improving the speed and the precision of the moment increase; and the manual locking and the automatic tracking of a moving object are realized by the platform by adopting an image tracking mode, thereby simplifying the work of operating personnel and effectively ensuring that stable and high-quality image information is obtained. The invention effectively isolates the interference caused by vehicle-mounted angular movement, inhabits the platform drift caused by the gyro, improves the dynamic performance of a system, and has important application value for the fields of film shooting and the like.

Description

technical field [0001] The invention relates to 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, border defense anti-smuggling evidence collection, and 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 must simultaneously solve the problems of isolating carrier disturbance and servo tracking. [0003] In order to solve the problem of isolating carrier disturbances, the current fil...
