An anti-jamming attitude control ground verification system based on an angular velocity observer and its control method

Abstract

The invention relates to an anti-interference attitude control ground verification system based on an angular velocity observer and a control method thereof. The ground verification system comprises an under-table master control module, a table-mounted control computer, an attitude determination module, an actuating mechanism module and a triaxial air bearing table. The ground verification systemis a type of general verification system. The attitude determination module selects different sensors of the module to be combined to verify failure of the sensors and multiple other conditions. The attitude control algorithm of the table-mounted control computer is selected through the under-table master control module so as to complete comparative analysis of different attitude control algorithms. The anti-interference attitude control method based on the angular velocity observer is operated on the table-mounted control computer so that the problems of poor reliability and low anti-interference capability of the attitude control system under the condition of angular velocity information loss and load disturbance can be solved. According to the ground verification system, the effectiveness of the anti-interference attitude control method based on the angular velocity observer can be verified, the control accuracy can be enhanced and the ground verification system is suitable for ground simulation verification of the aircraft control method.

Problems solved by technology

[0004] Attitude control system test devices have been widely used in the development of aircraft. The 502 domestic aerospace institutes, the 812 aerospace institutes, and Harbin Institute of Technology, Tsinghua University, Beihang University and other universities have developed attitude control system test devices, but now Some attitude control system test devices are usually developed for a specific type of aircraft, and some are only for a specific space mission. They are built to verify a specific method, ignoring the influence of load disturbances, lack of sensor information, and other different working conditions. The attitude control algorithm verification cannot be used for the research of various anti-jamming attitude control methods including those based on the fly angular velocity observer
