摘要
针对一类更具一般性的不确定多时滞非线性系统 ,在不确定项范数有界 ,但是其上界未知的情况下 ,设计自适应鲁棒 H∞ 状态反馈控制器 ,论证了该类系统的自适应 H∞ 鲁棒控制器存在的充分条件 ,并利用耗散性原理证明了这些充分条件。仿真结果表明该方法能较好地估计未知参数 ,并对干扰输入具有较强的抑制能力。
The paper dealt with a class of relatively simple uncertain systems with multiple time delay when the uncertainty was bounded but its upper hound was unknown. Then we put forward an uncertain nonlinear system, which is more general and in which we use H∞ control instead of robust control. We propose an adaptive H∞ control law together with an adaptive update law. An example was used to illustrate the step-by-step procedure for designing the proposed controller. The simulation results show that our design method not only can estimate the unknown parameters but also can attenuate the disturbance.
