Embodiment Construction

[0026] The multi-mode control and switching method of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] The multi-mode control and switching method of the present invention is realized through the following steps:

[0028] Step 1: Determine and divide the control modes of the flight control system.

[0029] The early drones were called RPV (Remote Pilot Vehicle), that is, remote piloted aircraft, which were completely controlled by the ground. With the continuous development of science and technology, fully autonomous flying drones have appeared. In the process of fully autonomous flight, the remote control signal still plays a different role in the flight of the UAV. Due to the needs of the UAV to perform tasks, during the flight, the ground operator can use the remote control signal to decide the aircraft to complete the actions such as circling, figure-eight flying, maneuvering flight, and fixed-altitude flight; ...

Abstract

The invention discloses a multiple modal controlling and switching method for an unmanned aerial vehicle, which determines and divides control modes of a flight control system into an autonomous control mode, a manual amendment control mode, a command control mode, a remote control mode with an innerloop and a remote control mode without the innerloop according to different action degrees and action effects of remote control signals to a flight control system, wherein, the autonomous control mode is a basic mode; the manual amendment control mode is flight control stage of precise postures and tracks mainly against taking off / landing, etc.; the command control mode is determined according to a flight assignment; the remote control mode with the innerloop and the remote control mode without the innerloop are spare modes. A switchover among the modes can either be actively selected according to an operator, the flight assignment or the current flight state, or be automatically entered according to the state of the system, thereby achieving a multi-modal controlling management, and inhibiting a transient response of the aerial vehicle during converting control laws of different modes.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle flight control, in particular to an unmanned aerial vehicle multi-mode control and switching technology. Background technique [0002] The fly-by-wire control system that appeared in the early 1970s overcomes the inherent defects of the mechanical control system, and also lays the foundation for the realization of other control functions. By adding appropriate feed-forward and feedback networks in the fly-by-wire control system, the input and output characteristics of the aircraft itself can be changed to make it have different flight qualities to meet the needs of different flight missions, thus forming multiple control systems in modern flight control. Multimodal control techniques for tasks. For example, the AFTI / F-16 aircraft tested and verified by the United States in the early 1980s adopted the multi-mode control law. In order to meet the needs of aircraft take-off, cruise and differ...
