| 摘 要： | 针对一类非线性多输入多输出不确定系统,基于小增益理论提出了鲁棒自适应模糊轨迹线性化控制方法.利用T-S模糊系统逼近未知干扰和不确定性因素,采用Lyapunov方法及小增益理论证明了闭环系统所有信号一致最终有界.该算法自适应律的学习参数仅有1个,便于工程实现.最后利用该文提出的控制方案设计了空天飞行器飞行控制系统,仿真结果表明了控制方案的有效性和鲁棒性.

| Abstract: | This paper presents a robust adaptive fuzzy trajectory linearization control(RAFTLC) based on the small gain theorem for a class of nonlinear multi-input multi-output(MIMO) uncertain systems.The unknown disturbances and uncertainties are approximated by a T-S fuzzy system,and the boundedness of all signals of the composite closed-loop system is guaranteed by Lyapunov method and the small gain theorem.This algorithm has only one adaptive parameter adjusting on line and is convenient to realize in engineering.Finally,a flight control system of an ASV is designed based on the proposed method.Simulation results demonstrate the effectiveness and robustness of the control scheme. |
