| 摘 要： | 基于简化的三轴稳定飞行器运动模型设计了线性二次型(LQR)最优跟踪调节器。为消除系统模型的不确定性,由微分几何精确反馈线性化理论设计了LQR输出反馈补偿器;对系统的外加干扰,考虑H∞控制的混合灵敏度设计了混合LQR-H∞控制器。仿真结果表明:该设计方法不仅使姿态控制系统有良好的跟踪特性,而且具一定的抗干扰能力,系统鲁棒性较强。

| Abstract: | The linear quadratic regulator（LQR） tracking adjuster was designed based on the simplified dynamic model of the three-axial aerocraft in this paper.The LQR export feed-back controller was designed using the feedback linearization approach of differential geometry.For the outer disturbance,a mixed LQR-H_∞ was designed while the mixed sensitivity was in consideration.The simulation results showed that this method could not only bring excellent tracking performance but also ensure anti-jamming performance,and the robust performance of the system was well. |
