The robust stability problem for uncertain linear delay-differential systems of neutral type is investigated. The norm-bounded uncertainty appears in all system matrices. A new delay-dependent stability criterion is derived. The criterion is formulated in the form of a linear matrix inequality (LMI). Numerical examples show that the criterion is much less conservative than those in the literature.
Robotic technology is enhancing surgery through improved precision, stability, and dexterity. In manual MIS, the surgeon is separated from the operation area, which is reached by long instruments. In image-guided procedures, image prediction technique based on visual reality technology has solved time-delay problem of image information between master and slave manipulator of teleoperation system effectively...
This paper investigates the problem of Hinfin control for offshore structures with persistent disturbances. The time delay is introduced into the controller as a positive factor to counteract the persistent disturbances, such as wind and wave loads. Using Lyapunov stability theory and an integral matrix inequality, a new bounded real lemma is derived and, based on this, an Hinfin controller with input...
This paper deals with the stability problem for a class of linear neutral delay-differential systems. The time delay is assumed constant and known. Delay-dependent criteria are derived. The criteria are given in the form of linear matrix inequalities which are easy to use when checking the stability of the systems considered. Numerical examples indicate significant improvements over some existing...
