摘要
针对滑翔再入飞行器(GRV)的解耦控制问题,基于微分几何方法和自抗扰控制,提出了一种具有自抗扰能力的鲁棒自适应解耦控制方法,该方法通过扩张状态观测器改进精确线性化方法,将多变量耦合不确定性系统转化为自抗扰非交互式系统,并通过自抗扰姿态稳定回路设计,改善解耦系统在不确定性和扰动条件下的鲁棒稳定性和控制品质,有效解决了GRV这类复杂系统的鲁棒解耦控制问题,并通过仿真研究验证了方法的可行性和有效性。
To solve difficult problems of Glide Reentry Vehicle （GRV） decoupling control,a new robust and adaptive decoupling control method with active disturbance rejection capability is proposed based on differential geometry method and active disturbance rejection control theory in this paper. Firstly,an advanced feedback linearization method based on Extended State Observer （ESO） is used to transform GRV attitude control model into the form of an active disturbance rejection noninteracting . control system. Secondly,an attitude active disturbance rejection stabilization controller is designed to guarantee system robust stability and improve control qualities. Finally,simulation results demonstrate the feasibility and validity of the proposed method.
