We analyze under which conditions linear time-invariant state space systems can be stabilized by static linear state feedback such that prescribed transient bounds hold pointwise in time for the trajectories of the closed loop system. We introduce the concepts of (M,β)-stability and quadratic (M,β)-stability which guarantee a transient bound M along with a decay rate β < 0. Necessary and suffic...

An all-optical feedback scheme in which the output of a cavity mode is used to influence the dynamics of another cavity mode is considered. We show that under ideal conditions, perfect preservation against decoherence of a generic quantum state of the source mode can be achieved.

A utomatic control teaching can be fragmented, comprising different streams that seem to be disconnec t ed or even competing. The appeal of new theories and concepts may encourage students to forget that the key issue in the discipline is the control design problem. If two or more different approaches provide a good solution to that problem, then a strong connection should exist between them. I...

this study is a typological description of written formative feedback in an efl context in iran. twenty m.a. students of tefl participated in the study. they were required to summarize a scholarly article in each session on which the instructor would provide written corrective feedback (cf). written formative comments were extracted, coded, and categorized into various types, such as asking for...

In this paper, a novel method is developed for designing the output feedback controller for Static Synchronous Series Compensator (SSSC). In the proposed method, the problem of selecting the output feedback gains for the SSSC controllers is changed into an optimization problem with a time domain-based objective function.Then, it is solved by using the particle swarm optimization (PSO) algorithm...

This problem arose f rom an a t t empt to make a general s tudy of reliability iii :cbinputerlike machines. The classic results 0f:von Neumann (yon Neumgnn; 19o6) deal only with networks which do not have any feedback. Thus a malfunction only causes the network to be in the incorrect State for a fixed length of t i m e . However ; a malfunction in the general case with feedback can cause an err...
