摘要
针对实际中线性时滞系统的时滞常数往往不能精确已知的缺点 ,对具有状态滞后的线性时滞系统提出一种对时滞常数的自适应控制方案 ,其控制器存在的充分条件由一个线性矩阵不等式 (LMI)的形式给出 ,并对整个闭环系统的稳定性进行了分析 .
To aim directly at shortcoming of the delay constant which are not precisely known for linear delay systems in practice, an adaptive control strategy for delay parameter is proposed in this paper. The dynamic linear systems having a delayed state with the input that comprises a linear combination of the state with delay as well as the estimation of delay are considered. The delay dependent controller is derived which the sufficient condition is given in terms of LMI. The stability of the closed loop system is analyzed.
