Tracking control on target signal for a class of uncertain neutral systems

Tracking control based on target signal for a class of uncertain neutral systems is investigated in this paper. An augmented error system is constructed by combining the control system with the target signal. Through a Lyapunov-Krasovskii function and some inequalities, a stability criterion in terms of LMIs is proposed for the auto-controlled system. Then a state feed-back control is designed for the augmented error system. And tracking control, where the target signal and error signal are utilized to help deduce the static error, is obtained for the original uncertain neutral system. A numerical example is given to illustrate the validity of our proposed method.
