高超声速飞行器的自抗扰控制器设计

摘要

This paper proposes the implementation of active disturbance rejection control C ADRC) for altitude and velocity tracking control of the longitudinal model of hypersonic vehicle which has an integrated airframe-propulsion system configuration. A set of nonlinear longitudinal equations of motion for the vehicle which include the CFD-generated aerodynamic, propulsion, and coupled aero propulsion data are developed. An ADRC controller including velocity and height loop is designed according to the feature of the hypersonic cruise vehicle. Simulation results demonstrate the effectiveness of ADRC design in tracking altitude and velocity commands.%由于采用机体一体化设计,吸气式高超声速飞行器的气动特性难以准确获知,建立的数学模型是极为不准确的;设计了一种自抗扰控制器(ADRC),分别设计了速度回路和高度回路的自抗扰控制器;仿真用高超声速飞行器的纵向模型对该控制器进行了验证,证明该控制方法能够有效地跟踪飞行器的高度和速度指令.
