Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0031] Since the relationship between the force and displacement of the passive lever in the prior art is fixed, when the aircraft flies from a certain altitude to another altitude, continuing to control the aircraft through the passive lever cannot bring intuitive height feeling. The aircraft control stick (active stick) proposed in this application can be adjusted in real time according to the flight status of the aircraft. When the height of the aircraft rises, the relationship between the force and displacement of the active stick will change, so as to provide the pilot with more realistic sensory information, and then Improve the quality of aircraft handling. How to control the movement of the drive mot...

Abstract

The invention provides an active control method for an airplane joystick. The airplane joystick is at least connected to one driving motor, force feedback can be provided for the airplane joystick through the driving motor, and the active control method comprises the steps of obtaining acting force applied to the aircraft control stick, angular displacement of the driving motor providing the forcefeedback of the aircraft control stick and current flight parameters of an aircraft; and determining the output force of the driving motor according to the acting force, the angular displacement andthe flight parameters, and determining the feedback displacement of the steering column according to the output force. According to the active control method and device for the airplane joystick, thereal driving feeling closest to the flight state can be provided for an aircraft driver.

Description

technical field [0001] The application belongs to the technical field of flight control, and in particular relates to an active control device for an aircraft control stick. Background technique [0002] The aircraft has developed to the stage of full power-assisted control system, and the pilot's control feeling has been completely provided by the human-sensing system. Such as figure 1 As shown, the existing human-sensing system uses the passive stick control device 10 to control the aircraft, that is, the aircraft control stick 11 provides the pilot with a sense of force through the load mechanism 12, damper 13, etc., but the relationship between the stick force and the stick displacement of the passive stick is fixed, and the gradient This feeling has nothing to do with the flight status of the aircraft. Contents of the invention [0003] The purpose of this application is to provide a method and device for active control of an aircraft control stick, so as to solve o...
