摘 要: | 以考虑光电跟瞄平台三轴环架间的耦合所建立的数学模型为基础,对光电跟瞄平台的稳定回路分别设计了基于线性矩阵不等式(LMI)的状态反馈H∞控制器和多输入系统极点配置控制器;分别建立基于所设计两种控制器的跟瞄平台稳定控制系统,并对其控制效果进行对比研究,结果表明,二者皆能实现对光电跟瞄平台的稳定控制,都具有一定的鲁棒性能。其中H∞控制器的设计更简单,超调更小且达到稳定的时间短,更适合于光电跟瞄平台的稳定控制。

Abstract: | This article is based on the mathematical model which is applying to the design of controller,considering coupling of three-axis frame,respectively design state feedback H∞control based on linear matrix inequality (LMI) and pole assignment stability controller. Set up the two kinds of stability control system of tracking-pointing platform based on the designed controllers,then,the control effect is compared,results showed that,both design could realize stability control,have some robustness. Especially,H∞controller design is much simpler and has a smaller overshoot,time achieving stable is short,witch is more suitable for the stabilization control of electro-optical tracking and pointing system. |
