Multi-axis quick attitude maneuver jetting control method

Abstract

The invention discloses a multi-axis rapid attitude maneuver jet control method, which comprises: the aircraft obtains the deviation quaternion corresponding to the target attitude angle from the current attitude angle; the aircraft combines the PD control method with the deviation quaternion according to the maximum maneuvering angular velocity The number is subjected to limiting processing; the aircraft decomposes the deviation attitude angles of the three channels of roll, pitch, and yaw according to the limited deviation quaternion; the aircraft uses the PD control method to obtain the attitude maneuvering jet control command. The present invention overcomes the singularity brought by the description of Euler angles when the star is maneuvering at a large angle; by limiting the maximum maneuvering angular velocity through equal-proportional limiting of the deviation quaternion and combining with the PD control law, the optimal path can be achieved The multi-axis rapid attitude maneuvering control ensures the safety of maneuvering at the same time.

Description

technical field [0001] The invention relates to the technical field of satellite attitude maneuver control, in particular to a multi-axis rapid attitude maneuver jet control method with limited angular velocity. Background technique [0002] Ordinary earth observation satellites often do not require multi-axis simultaneous rapid attitude maneuvers, which are usually described by Euler angles, and path planning is used to ensure the stability of maneuvers; in addition, general satellites use jets as actuators When using oblique switch line or phase plane control, it is difficult to debug because it needs to set multiple sets of parameters to take into account the stability control and maneuvering control performance. [0003] In the current state, aircraft generally not only require earth observation, but also require multi-axis maneuvering within a specified short period of time in order to achieve specific tasks. Contents of the invention [0004] The invention provides ...
