垂直/短距起降飞机的控制仿真技术

Control simulation technique of SVTOL aircraft

针对垂直/短距起降飞机的特点,通过在某型飞机上虚拟加装升力风扇系统,建立了垂直/短距起降飞机的动力学模型,提出了垂直起降阶段垂向、纵向、横向和航向的控制方式并完成了控制律的设计与验证。研究结果表明,所建立的垂直起降动力学模型能够描述垂直起降飞机的动力学特点,提出的控制方式和设计的控制律能够有效地控制飞机实现垂直升降、侧飞、偏航、前飞和后飞等运动,可用于垂直起降飞机的飞行品质、起降程序的设计和验证等相关方面的研究。

For the characteristics of SVTOL aircraft, a flight dynamics model of the SVTOL aircraft was built based on a certain aircraft of a virtual lift fan system. Then the vertical, longitudinal, lateral and di- rectional control scheme during the vertical take-off and landing period is given out. The control law is designed and verified as well. The results show that the SVTOL dynamics model can accurately describe the dynamics characteristics of SVTOL aircraft. The control scheme and the control law designed before are available to handle the aircraft to take off and land vertically, side fly, yaw, fly forward and back. The model can be applied to the related research of design and validation of flight quality, SVTOL procedure.
