摘　　要：提出了一种利用自抗扰控制器算法设计超机动飞行快回路控制律的新方法.根据自抗扰控制器能够动态补偿系统模型扰动和外扰的特性,在超机动飞行的快回路中引入自抗扰控制器,实现了快变量的动态解耦控制.控制律设计直接依据超机动飞行的强耦合、强非线性模型,在较大的包线范围内不需要改变控制器参数,简化了设计过程.仿真结果表明,系统具有良好的动态和稳态性能,控制器具有很强的鲁棒性.By using Auto-disturbances-rejection-controller （ADRC）, a new scheme is proposed to design controller for fast variable system of super-maneuverable flight. The new scheme realizes the decoupling control of fast state variables by applying ADRC in the fast variables system to compensate model disturbances and uncertainty. Based on the nonlinear and coupling model of aircraft, ADRC is specially fit for super-maneuverable flight control design that is nonlinear and has big model disturbances. Furthermore, without changing the structure and parameters of the controller in big flight envelope, the scheme can simplify the design of flight control system. The simulation results show that the closed-loop system achieves high dynamic performance and robustness.
