Abstract: To further strengthen the robust control of Lurie system,based on the early theoretical study,a controller design theory for Lurie systems with time-varying delay uncertainty is discussed with the application of the new cross-term definition method. By constructing a new Lyapunov functional and following the characteristics of Lurie system,the new feedback controllers are designed for singularly perturbed Lurie systems with uncertain time-varying delay in the sector region [V1,V2],and the state feedback control laws of time-delay dependent and time-delay independent are deduced. Finally,the feasibility and effectiveness are illustrated by the correspanding numerical example.

Key words: lurie systems, strongly absolute stability, state feedback control law, cross terms defined method, delay-dependent, delay-independent, lyapunov-krasovskii functional ( L-K ) , linear matrix inequality ( LMI)
