Discontinuous Discrete Systems of Analysis

Stability of Dynamical Systems — Continuous , Discontinuous , and Discrete Systems

Ihave always believed that stability is the most important concept in systems and control theory. From the early days of my undergraduate studies, when I was first exposed to Lyapunov theory, to these days in which I devote a significant proportion of time to proving stability properties of dynamical systems and teaching stability to secondand third-year undergraduate students, I have never cea...

Decentralized prognosis of fuzzy discrete-event systems

This paper gives a decentralized approach to the problem of failure prognosis in the framework of fuzzy discrete event systems (FDES). A notion of co-predictability is formalized for decentralized prognosis of FDESs, where several local agents with fuzzy observability rather than crisp observability are used in the prognosis task. An FDES is said to be co-predictable if each faulty event can be...

Discrete analysis systems.

Discrete analysis systems are so called because the samples are treated and carried through the major part of the analytical process in separate containers. Such systems can be very simple involving only a diluting module and a colorimeter or be highly sophisticated multichannel machines. Up to the present time laboratory automation (or strictly 'mechanization') has been dominated by the contin...

Optimal Finite-time Control of Positive Linear Discrete-time Systems

This paper considers solving optimization problem for linear discrete time systems such that closed-loop discrete-time system is positive (i.e., all of its state variables have non-negative values) and also finite-time stable. For this purpose, by considering a quadratic cost function, an optimal controller is designed such that in addition to minimizing the cost function, the positivity proper...
