On the other hand, switched systems are systems with dynamic switching and can be used to model real systems whose dynamics are chosen from a family of possible choices according to a switching signal [19].
In [110], the convergence of the GIKF scheme has been analyzed and the error covariance is shown to evolve according to a switched system of random Riccati operators where the switching is governed by a Markov chain determined by the network topology.
We shall contrast the standard controller with a similar feedback PD controller, with the difference that the feedback is switched on and off intermittently, according to a switching mechanism defined in the phase plane.
The proposed methodology is based on a minimum-distance mode estimator which orchestrates controller switching according to a dwell-time switching logic.
Under the assumption that the coopetition network is structurally balanced and the leader is a root of the spanning tree in an augmented graph, the bipartite consensus and the parameter estimation are analyzed by invoking a common Lyapunov function method when the coopetition network is time-varying according to a piecewise constant switching signal.
They can promote cancer progression by their resistance to drugs or, according to a recent study, switching of functions [ 23].
And according to a recent United Nations report, switching to cleaner energy sources would require investments of up to $20 trillion over the next two decades.
Nearly half of the households that could lose television service after the transition to digital broadcasting are still unprepared for the switch, according to a report released yesterday by the Government Accountability Office.
Some 9.5% of U.S. workers between the ages of 44 and 70 have moved into the social sector (nonprofits, schools, and other civic institutions), and half of "trailing edge" boomers between 44 and 50 say they, too, want to make the switch, according to a recent survey by the MetLife Foundation and Civic Ventures.
Given how easily a first choice of major can be swayed by accidents of timing and environment, it's perhaps not surprising that 37percentt of students eventually switch, according to a new paper from University of Memphis economists Carmen Astorne-Figari and Jamin D. Speer that will be published in the journal Economics of Education Review.
