Abstract :
This paper deals with a robustly stable adaptive pole-placement based controller for a class of linear time-invariant time-delay systems with possibly locally unknown point delays under unmodeled dynamics and bounded disturbances. A multi-estimation scheme is used to improve the identification error and also to deal with possibly errors between the true basic delay compared to these used in the regression vectors of the adaptive scheme
