针对一类带输入时滞且状态时滞常数未知的线性时滞系统,基于LMI方法,采用一种Lyapunov-Krasovskii函数和新型带记忆的状态反馈控制,突破以往自适应控制对估计值的大小限制,研究了一种新型的对该类系统未知状态时滞常数进行自适应控制的控制器设计问题,并且通过带记忆控制器中的常数的适当选取使得带记忆控制始终能反映未知时滞,仿真例子显示了该种方法的有效性. For a class of linear time-delay systems with input delay and unknown state delay constant, based on the LMI method, a Lyapunov-Krasovskii function and a novel state feedback control with memory are used to overcome the limitation of the previous adaptive control , A new type of controller design problem for adaptive control of unknown state delay constant of this kind of system is studied. With the proper selection of constants in the memory controller, the memory control can always reflect the unknown delay. The simulation The example shows the effectiveness of this approach.
