在飞机研制过程中,为保障研制过程的顺利,提高试飞成功概率,需要对飞机进行地面模拟实验。飞机航空泵在地面测试过程中,其驱动结构包括变频调速器、异步电机和增速箱。本文通过对建立航空泵试验台驱动系统各环节的数学模型和对转速的滑模变结构的控制,模拟航空泵试验台系统运作,为研究航空泵试验台驱动变结构控制提供参考依据。 In the process of aircraft development, in order to ensure the smooth development process and improve the probability of successful flight test, it is necessary to conduct ground simulation experiments on the aircraft. Aircraft air pump in the ground test process, the drive structure, including the inverter, induction motor and gearbox. In this paper, the mathematical model of the drive system of the aeronautical pump test bench and the control of the sliding mode structure of the rotational speed are established to simulate the operation of the test system of the aeronautical pump, which provides a reference for the research on variable structure control of the aeronautical pump test bed.
