自抗扰控制器的飞机纵向运动控制律设计

为了实现较大包线内飞行速度和俯仰角变量的解耦控制，根据自抗扰控制器可以动态补偿系统模型扰动和外扰的特点，提出了利用自抗扰控制器对飞机纵向运动进行解耦控制的新方法。在飞机纵向回路中引入自抗扰控制器，实现了纵向速度和俯仰角变量的解耦控制。直接针对飞机的非线性模型设计的自抗扰控制器在很大的包线范围内不需要改变控制器的结构和参数，简化了设计过程。大包线范围内的仿真结果表明，系统具有良好的动态性能，控制器具有很强的鲁棒性。

Control law design of aircraft longitudinal movement based on auto disturbances rejection controller

In order realize decoupling control of flight speed and pitch angle,based on the feature of model disturbances and uncertainty being compensated dynamically in auto-dsturbances-rejection-controller(ADRC),a new method using ADRC is proposed for the decoupling control of aircraft longitudinal movement and the decoupling control is realized by applying ADRC.Furthermore,the design of flight control system is simplified by the scheme proposed without changing the structure and parameters of controller in big flight envelope.Simulation results show that the high dynamic performance and robustness performance can be achieved by proposed method.
