Problems solved by technology

[0002] The electro-hydraulic servo force coordinated loading control system of the aircraft door mechanism is a typical follow-up load method. Due to the fast response of loading requirements (16.4CM / 0.55S / 1KN) and the drastic changes in the motion state, the speed conversion gradient is large (opening the cabin 0.5S-keep 50S-closed cabin 0.9S-keep 50S), using fixed PID adjustment parameters is not easy to control at the moment of motion conversion

Embodiment Construction

[0013] A control method for the loading equipment of the hatch mechanism, which calculates the deviation e(k) of the hatch speed change according to the hatch motion state data collected by the system, and adjusts the PID parameters in a segmented control mode, wherein

[0014] When the deviation e(k)>E, take the control quantity u(k)=u(k-1)ΔU

[0015] Among them, E is a constant, indicating a threshold value for judging the movement state of the hatch, which is adjusted according to different working conditions. A negative number indicates that the direction of the movement state is opposite, and it is positive here in the opening and holding section. ΔU is a constant, expressing the electro-hydraulic servo in the loading actuator Valve control amount, where the opening holding section is positive; u(k) represents the control amount of the electro-hydraulic servo system valve;

[0016] When 0

Abstract

The invention is used in an electro-hydraulic servo coordination loading control system of a plane cabin door mechanism, and particularly relates to a control method for a cabin door mechanism loading device. The loading of the plane cabin door mechanism electro-hydraulic servo coordination loading control system is in a typical follow-up load mode. The invention provides a segmented PID control method. The segmented PID control method calculates a cabin door speed change deviation e(k) according to collected cabin door state data and adopts a segmented asymmetric PID control parameter according to different deviation values in order to achieve a goal of adjusting the controlling parameter in an intelligent manner. A designed control system is feasible and high in reliability, and can satisfy a system loading performance requirement.

Description

technical field [0001] The invention is used in an electro-hydraulic servo force coordinated loading control system for a cabin door mechanism of an aircraft, and in particular relates to a control method for loading equipment of a cabin door mechanism. Background technique [0002] The electro-hydraulic servo force coordinated loading control system of the aircraft door mechanism is a typical follow-up load method. Due to the fast response of loading requirements (16.4CM / 0.55S / 1KN) and the drastic changes in the motion state, the speed conversion gradient is large (opening the cabin 0.5S-keep 50S-closed cabin 0.9S-keep 50S), using fixed PID adjustment parameters is not easy to control at the moment of motion conversion. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a segmented PID control method, calculate the hatch door speed change deviation e(k) according to the hatch system state data collected by the syst...
