Description

technical field [0001] The invention relates to an advanced controller design method for active side sticks, which belongs to the technical field of civil aircraft active side stick control. Background technique [0002] The main components of the active side stick system include: a handle, a joystick, vertical and horizontal motors, force-displacement sensors and the controller involved in the present invention. The basic principle is to adjust the "force-displacement" characteristic of the control stick through the principle of electronically controlled man-stick, and feed back the status information of the aircraft, thereby enhancing the driver's "situational awareness" and obtaining better maneuverability. At the same time, the active sidestick system can follow the instructions of the pilot during automatic driving, so that the driver feels that the instructions of the pilot are followed. Along with the application of the fly-by-wire flight control system in civil airc...
