摘要
无人机控制系统随其功能的增加而日益复杂,控制变量也随之增多;大的机动性能导致通道间的耦合增强,采用经典单变量控制的设计方法不能满足多变量控制系统性能的需要。多变量控制技术为复杂控制律的设计提供一个有效的手段。基于线性多变量控制理论对无人机横侧向通道进行设计,实现对制导指令的跟踪并对其进行解耦,并对所设计的控制系统进行鲁棒性分析。仿真结果表明基于多变量控制理论所设计的系统具有良好的跟踪能力和较强的鲁棒性能。
The control system of UAV became more and more complexity while its functions increase,and the more variables was needed to be controlled.The super-maneuverability caused the seriously coupling among channels.The design philosophy based on a loop-at-a-time can not meet the needs of the system performance.Multivariable control techniques provided an effective means to design complicated control laws.The control law was design for the UAV lateral-directional channel based on linear multivariable control theory and tracking the output commands of the guidance system is achieved.The robustness analysis of the designed control system was carried out.Simulation results indicate that the system designed based on multivariable control theory provides good tracking ability and strong robustness.
