Airborne-antenna high speed servo motion platform

Abstract

The invention discloses an airborne-antenna high speed servo motion platform. By using an existing airborne-antenna servo motion platform, an antenna can not be driven to carry out high-speed and high-precision scanning motion. By using platform of the invention, the above problem is solved. The platform comprises an orientation motion component (1), a pitching motion component (2), a power amplifier module (3) and a control and interface module (4). The control and interface module (4) generates a pulse width modulation signal which is used to control a motor and outputs to the power amplifier module (3) according to a received control instruction, aerial carrier attitude data and feedback signals of orientation and a pitch angle. The power amplifier module generates a motor driving power supply according to a received pulse width modulation control signal, outputs to the orientation motion component (1) and the pitching motion component (2) so as to drive the two components to carry out orientation and pitching motion, and simultaneously feeds back the orientation and the pitch angle to the control and interface module (4) in real time. The platform possesses advantages that a response speed is fast and control precision is high and can be used in various aircrafts which need the antenna to carry out mechanical scanning motion.

Description

technical field [0001] The invention belongs to the technical field of servo control, and in particular relates to a servo motion control, which can be used for the servo motion control of mechanical scanning of airborne radar antennas of various aircrafts. Background technique [0002] The airborne antenna servo motion platform is used to drive the radar antenna of the airborne aircraft to move in the azimuth or pitch direction according to a certain rule. As an important part of the airborne radar, its performance directly affects the performance of the airborne radar system. The antenna servo motion platform receives the instructions of the on-board radar system, and drives the antenna to scan in azimuth or pitch according to the requirements of the radar system, or drives the antenna to move in other ways. At the same time, the antenna servo motion platform needs to transmit the azimuth and pitch angle information to the radar system, so that the radar system can accurat...

AI Technical Summary

Problems solved by technology

[0003] At present, the airborne antenna servo motion platform mostly adopts the transmission mode of motor accelerator or gear. Due to the influence of gear gap and gear elastic deformation, the response speed of the antenna servo motion platform is slow and the accuracy is poor. When the control circuit adopts analog circuit When controlling, its flexibility is also poor
