针对无人机受参数摄动和外界扰动影响的特点,对 H_2/H_(?)混合控制控制理论在无人机飞行控制系统中的应用进行了研究。对典型无人机的横航向飞行控制系统,用混合 H_2/H_(?)鲁棒控制方法设计状态反馈控制器,使飞机控制系统在鲁棒稳定条件下,满足一定的性能指标。利用线性矩阵不等式在求解多目标综合控制问题方面的优势对问题进行求解,仿真结果表明控制器具有较好的扰动抑制能力和跟踪性能。
Aiming at the characteristics of UAV affected by parameter perturbation and external disturbances, the application of H 2 / H_ (?) Hybrid control theory in UAV flight control system is studied. For a typical UAV flight course flight control system, a hybrid H 2 / H_ (2) robust control method is used to design a state feedback controller to make the aircraft control system meet certain performance under robust and stable conditions. Solve the problem by using the advantages of linear matrix inequality in solving multi-objective integrated control problems. The simulation results show that the controller has good disturbance rejection and tracking performance.
