    In Cyber-Physical Systems large numbers of heterogeneous cyber and physical subsystems are networked, are interacting tightly, may change dynamically and may expand or contract. Designing and preserving properties of a CPS over its lifespan is very challenging. Passivity and dissipativity are energy like concepts that offer great promise in guaranteeing properties, such as stability, in complex he... View full abstract»

    Control science is basically a model based discipline. The performance of control is determined by the accuracy of the model representing data. Therefore the successes of identification reflects into the successes of control. This is why identification and control have had a never-ending interplay over so many decades. In this paper we try to outline such interplay by making reference to one of th... View full abstract»

    This paper addresses issues relating to the modeling and control of grinding mill circuits as used in minerals processing, with a particular emphasis on (semi) autogenous grinding or SAG mills. SAG mill circuits are generally difficult to control due to the presence of strong external disturbances, poor process models and the unavailability of important process variable measurements. In addition, ... View full abstract»

    A higher dimensional system which has a normally nonhyperbolic periodic manifold is studied in this paper. Assume that the system has an invariant manifold, which consists entirely of periodic orbits and has a center subspace with two dimensions in normal direction. By using exponential trichotomy, Poincare map and the implicit function theorem, the existence of the subharmonic orbits is given. View full abstract»

    Because of the common phenomenon of coupled time-varying delay in the complex dynamical networks, the problem of impulsive synchronization in output coupled complex dynamical networks is investigated in this paper. In order to achieve synchronization of each node of a time-varying delayed complex network, we design an impulsive controller using output signals. Sufficient conditions are derived on ...
