Abstract

The invention belongs to the technical field of electromechanical and optical integration and automation control, and discloses a multi-beam antenna adjustment platform and a control system and methodthereof. An upper computer sends an instruction to a motion controller, an upper platform pose of a control mechanism revises the pointing of an antenna reflector fixedly connected on the upper platform pose, a magnetostrictive displacement sensor detects data in real time and reports the data to the upper computer, the upper computer uses a mechanism positive solution algorithm to calculate an actual platform pose, the actual platform pose is compared with an ideal pose, an adjustment platform pose is revised to form a closed loop feedback system; in the motion controller, an embedded systemframework is adopted, a discrete S-type acceleration and deceleration curve based on a time-position mode is used, control information is calculated combined with a mechanism inverse solution algorithm, and the adjustment platform is controlled to move according to a predetermined trajectory. The multi-beam antenna adjustment platform has the advantages that the installation of an antenna systemis convenient, the stability is good, the control precision is high, the upper platform pose is accurately controlled, the pointing of the multi-beam antenna reflector is accurately adjusted, and theproperty of the multi-beam antenna is improved.

Description

technical field [0001] The invention belongs to the technical field of electromechanical-optical integration and automatic control, and in particular relates to a multi-beam antenna adjustment platform and its control system and method. Background technique [0002] With the advancement of science and technology, human beings have higher and higher requirements for satellite communication systems. Traditional satellite antennas can no longer meet the needs of scientists for space exploration. Compared with traditional antennas, reflective multi-beam antennas can It covers a large ground area and greatly improves the capacity and efficiency of satellite communication. Therefore, it is widely used by various countries and plays an important role in modern wireless communication and radar systems. The feed source and feed slide rail of the multi-beam antenna are installed on the antenna reflection surface. In order to expand the coverage area of ​​the antenna, the multi-beam an...
