Networked Control Systems are becoming very popular nowadays. However, the use of networks in the control loop induces extra difficulties in diagnosis. In this paper we propose a method for estimate fault as well delay induced by the network. Inspired from the Kalman filter previously proposed by Sinopoli et al. and Hsieh et al., two solutions are presented; the augmented and the two-stage Kalman...
This paper deals with the output feedback generalized H2 control for a class of discrete-time fuzzy systems with interval time-varying delay. Based on piecewise Lyapunov-Krasovskii functional, a LMIs characterization is established to guarantee the asymptotically stability and generalized H2 performance of the resulting closed-loop system. Explicit expressions of a desired output feedback controller...
In systems with deterministic and constant delay Smith predictor offers a very efficient method for compensating dead-time. However, it is vulnerable to model uncertainties and parameter changes, in particular to delay variations. In this paper, we provide an alternative solution for compensating dead-time in systems with uncertain and time-varying delay. Two compensator structures are proposed -...
Applications of bifurcation theory have been employed in all engineering branches, especially in control. In this paper we analyse one control application to delay differential equations based on mentioned bifurcation theory. The time response of a first order delay model with saturation effects has been studied. A stability parameters map, showing the boundaries which separate zones with different...
