Adaptive Control for Linear Delay Systems to Aim Directly at Delay Parameter
线性时滞系统对时滞参数的自适应控制

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.
