摘要
常规的特征结构配置(EA)方法不能同时满足系统频域设计指标和鲁棒稳定性的要求,而H_∞鲁棒控制理论在设计控制器时,并没有考虑系统时域性能。为此,基于特征结构配置和H_∞鲁棒控制,设计一种直观的控制器。该控制器以特征结构配置作为内环控制器,以H_∞鲁棒控制器作为外环控制器,使闭环系统能同时获得较好的时域动态特性、鲁棒稳定性以及指令跟踪性能力。通过对某无人机横侧向飞行控制的仿真,进一步验证了该方法的有效性。
The general eigenstructure assignment can not satisfy the requirement of both the frequencydomain design index and robust stability of the system.H_∞robust control theory doesn＇t consider the time domain performance when it design controller.Therefore,An intuitive controller is designed based on eigenstructure assignment and H_∞robust control theory.Utilizing eigenstructure assignment as the inner controller and H_∞robust controller as the outer loop controller,we make the closed-loop system a better time-domain dynamic performance,robust stability and the command tracking performance.In the end,a simulation of a UAV lateral flight control is given.The simulation results indicate that the approach is effective.
