Analysis on control system of transport aircraft cabin door's electrohydraulic system in virtual flow

By now, few researches of the transport aircraft have been carried out in our country, reason is because the transport aircraft has a big size which will raise the design cost in the wi As a result, the development of the air-function experiment is at a standstill. In the backgroi transport aircraft cabin door's electrohydraulic system, the Dryden wind field and the (1-cosin gust were used to build the stochastic wind field. Then, the open and keep-process of the car stochastic wind field could be observed. The analysis result shows that the system has a vibration. A first-order process was used to modify the control signal. This change removes the vibration which is caused by the shortness of the unlocking duration, and makes sure the gate opening is more reliable.
