Embodiment Construction

[0051] The present invention will be described in detail below in conjunction with the accompanying drawings and examples. The control object of the present invention is a satellite cone-rod type capture mechanism (satellite capture mechanism for short), generally includes three parts for this type of capture mechanism, as figure 1 As shown, that is, the sequentially connected guide damping device a, pawl expansion device shell b, and extendable on-board device c, as well as pawl expansion device d installed inside the first three; the main function of the extendable on-board device c It is to drive other components to extend to the engine nozzle e through its extension. According to actual needs, a multi-stage sleeve structure can be adopted. The guide damping device a is located at the front end of the entire catch mechanism before the catch, and its head generally adopts a tapered surface structure. In order to protrude the internal ratchet expansion device when catching, ...

Abstract

The invention discloses a real-time control system and a real-time control method for a high orbit satellite cone lever capture mechanism. A front end sensor measuring unit measures the corresponding position and posture of a service aircraft and a target aircraft and the corresponding position of the capture mechanism and the inner wall of an engine spray tube of the target aircraft at real time; a capture structure controller judges the received corresponding position and posture at real time, when the service aircraft and the target aircraft reach the limit distance and the posture is matched and the capture command is received, the command is sent for controlling the straight line transmission motor for rotating, an extensible satellite borne device is used for driving other parts of the capture mechanism for extending into the spray tube of the target aircraft, the angle between the axis of the capture mechanism and the axis of the spray tube and the distance between the capture mechanism and the choke tube are confirmed; when the guide damp device at the front end reaches to the choke tube, the command is sent for controlling the cone lever for controlling the motor for rotating and driving the pawl tightening device for passing through the choke tube, the command is sent for controlling the motor for rotating reversely, the pawl tightening device is clamped at the choke tube for finishing capturing the target aircraft.

Description

technical field [0001] The invention relates to a control method for a cone-rod type capture mechanism, in particular to a real-time control method for a cone-rod type capture mechanism used for high-orbit satellites. Background technique [0002] High-orbit satellites play an important role in military and civilian fields such as communications, navigation, early warning, and remote sensing due to their large satellite coverage and relatively slow motion on the ground. Carrying out on-orbit service for high-orbit satellites can prolong the life of the satellite and improve the ability to perform tasks, which is one of the current research hotspots at home and abroad. In the process of on-orbit service for high-orbit satellites, operations such as auxiliary orbit change, fuel supply, attitude control, satellite takeover, and fault repair can be performed on the on-orbit satellite as needed. During this type of operation, satellites need to be captured and released under spe...
