摘要
以某无人机为背景,主要研究大机动时带推力矢量的综合飞行/推进控制系统的设计方法。应用非线性动态逆方法,根据无人机本身具有明显不同时间尺度差异的动力学特性,结合奇异摄动理论将控制变量按照响应快慢分为4个回路进行了控制器的设计与仿真;设计推力矢量控制和气动控制相结合的控制器,实现飞行和推力矢量的控制综合;将无人机的任务转化为对飞行控制的限制条件,对所设计的控制系统进行了数字仿真,结果表明所设计的控制器能够满足飞机做大机动时的控制要求。
A study on the integrated flight and propulsion control system （IFPCS） with the thrust vectoring for a certain type of unmanned aerial vehicle （UAV） is carried out. The nonlinear dynamic inversion is adopted to design flight control law of the nonlinear control system based on the UAV. The singular perturbation method is used for the time response characteristics of the UAV state variables. Thus, the complexity of controller design is divided into four layers. The integrated control system using thrust vectoring control （TVC） and pneumatic actuator control is designed The mission of UAV is transformed to the constraints of the flight control system. It is shown from the simulation results that the controller designed meets the needs for high maneuvering flight of UAV.
