Problems solved by technology

[0011] In the second scheme, when the buffer zone is large enough, although the follow-up control method can ensure that the shape of the trajectory is consistent with the requirements of the simulated aircraft, there is a fixed delay in time, and the delay is related to the size of the buffer zone.
Usually the delay required by flight simulation does not exceed 60ms, too much delay will also cause false motion hints

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a motion tracking method and device for a flight simulation electric motion system. Background technique [0002] In the flight simulation system, the motion system should drive the attitude change of the motion platform in real time according to the motion state of the simulated aircraft, so as to produce a realistic cockpit motion feeling. Among them, the follow-up control algorithm of the motion platform is one of the key technologies. [0003] The motion system is divided into a hydraulic motion system and an electric motion system according to the driving method, and the two have great differences in response characteristics. Hydraulic motion systems have been used in the field of flight simulation for a long time, and related technologies including motion platform follow-up control are relatively mature. In comparison, domestic electric motion systems have been used in the ...
