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。
Aiming at the problem of decoupling control of gliding reentry vehicle (GRV), a robust self-adaptive decoupling control method based on differential geometry and auto disturbance rejection control is proposed. The proposed method is based on the extended state observer By improving the accurate linearization method, the multivariable coupled uncertain system is transformed into a self-disturbing non-interactive system and the robustness of the decoupled system under uncertainties and perturbations is improved by designing a self-resistant disturbed attitude stable loop Sexual and control quality, and effectively solve the robust decoupling control problem of complex systems such as GRV. Simulation results show the feasibility and effectiveness of the proposed method.
