| 摘 要： | 将特征结构配置与直接自适应理论相结合对飞机侧向飞行控制律进行设计.首先介绍了特征结构配置的原理和反馈增益矩阵的算法实现,在此基础上结合直接自适应方法对闭环系统进行鲁棒控制器设计.该控制策略以特征结构配置作为内环控制器,自适应控制器作为外环控制器,使系统获得较好的动态性能和较强的鲁棒性.某飞机的侧向飞行控制律设计仿真结果表明系统获得了良好的动态性能,并且有效抑制了内部参数摄动对系统的不良影响.

| Abstract: | Modern high performance aircraft needs more advanced fight control systems,while it is more difficult to design these systems by using the classical control theory only.A design technique using eigenstructure assignment and direct adaptive controller for FCS is presented.Eigenstructure assignment can satisfy specifications in terms of dynamic response,while direct adaptive ensures good robust performance of closed-loop system.The simulation results show that the designed system based on eigenstructure assig... |
