| 摘 要： | 针对无尾无人机跟踪系统的特性,加之所研究的是多输人多输出(MIMO)系统,运用LQG/LTR方法进行控制器的控制律设计;仿真效果通过时域分析和频域奇异值伯德图分析相结合的方式实现,仿真结果表明运用该方法所设计出的控制律具有良好的鲁棒性和解耦性,能够较之经典设计方法更好地完成设计要求,设计步骤清晰;这种方法可以应用于其它控制对象。

| Abstract: | In the course of following system design of a tailless UAV,the controllers are designed implementing LQG/LTR.As the con- trol object is MIMO system,the simulation effect is realized with both time-domain and frequency-domain Singular Value Bode analysis. The simulation results show that the obtained control law satisfies the flying quality and has good robustness and decoupleness,and the de- sign requirement can be obtained properly.The method can be applied to other control objects. |
