摘　　要：考虑一类状态时滞系统模型参考鲁棒自适应控制问题 ,针对状态连续时滞动态系统 ,首先提出一个关键假设 ,然后基于该假设 ,应用 Lyapunov稳定性理论给出一种直接鲁棒自适应控制算法 .该算法保证闭环系统是实用稳定的 (所有信号最终一致有界 ) ,且与时滞无关 .因此 ,结果可以应用于带有时滞不确性的动态系统 .最后 。The problem of adaptive control of time varying delay systems is considered. Here the authors assume that the state uncertainties satisfy the key assumption. An algorithm of direct adaptive control for the plant is proposed based on the key assumption and Lyapunov stability theory. As the proposed controller can always guarantee uniform asymptomatic stability of the closed system and is independent of the delay , the results obtained in this paper are applicable to dynamical systems without exact knowledge of delay. A numerical example is given to demonstrate the validity of the results.
