In presence of large uncertainty, traditional methodologies based on a single controller do not provide, in general, satisfactory performance when applied to any system in the uncertainty set, and may not even guarantee stability. A way to address this problem is to consider a set of candidate controllers and design a supervisor that appropriately orchestrates the switching among them, based on...

Many physical systems are hybrid in the sense that they have continuous behaviors and discrete phenomena. In control system with multiple models, switching strategy and stability of the closed-loop system under switching are very important issues. In this paper, a novel adaptive control scheme based on multiple parameter models is proposed to cope with a change in parameters. Switching strategy...

Switching system is very important in the fields of industrial manufacture, chemical process, intelligent control, which have attracted much attention in recent years. It is well known that the phenomenon of time delay and nonlinear disturbance exist in the actual switching system, so the research on nonlinear time delay switched systems has great theoretical significance and practical value. I...

Absfrncf We propose a scheme for expanding switch modules to form a larger switch using the so-called focnl switching obtained by allowing bidirectional connection to the conventional three-stage Clos network switch. The performance of the proposed expansion architecture was compared to that of the conventional three-stage Clos network. We simulated 32x32 switching systems using two expansion a...

A switched system is a hybrid dynamical system consisting of a family of continuous-time subsystems and a rule that governs the switching between them. This paper surveys recent developments in three basic problems regarding stability and design of switched systems. These problems are: stability for arbitrary switching sequences, stability for certain useful classes of switching sequences, and ...

This paper investigates the asymmetric effects of monetary policy on economic growth over business cycles in Iran. Estimating the models using the Hamilton (1989) Markov-switching model and by employing the data for 1960-2012, the results well identify two regimes characterized as expansion and recession. Moreover, the results show that an expansionary monetary policy has a positive and statist...
