针对带有交叉耦合的多输入CE150直升机系统,设计了Fuzzy-LQG控制器。介绍了CE150直升机系统的组成及其数学模型,基于模糊控制论,建立了模糊规则库,并设计了Fuzzy-LQG控制器,对直升机系统的飞行角度和角速度进行了实时控制,与常规PID、LQG控制方法进行比较表明,Fuzzy-LQG控制方法具有更快的响应速度,更好的稳定性和鲁棒性。
Fuzzy-LQG controller is designed for multi-input CE150 helicopter system with cross-coupling. The composition and mathematical model of the CE150 helicopter system are introduced. Based on the fuzzy control theory, a fuzzy rule base is established and a Fuzzy-LQG controller is designed. The flight angle and angular velocity of the helicopter system are controlled in real time. Compared with the conventional PID, LQG The comparison of control methods shows that Fuzzy-LQG control method has faster response speed, better stability and robustness.
