— In the recent paper  a sufficient condition for Input-Output Finite-Time stability (IO-FTS) has been provided by the authors. By using an approach based on Reachability Gramian theory, in this paper we show that such condition, which requires the solution of a feasibility problem involving differential linear matrix inequalities (DLMIs), is also… (More)
— In this paper the problem of input–output finite– time stability (IO–FTS) and stabilization of linear time–varying systems is dealt with. The classical definition of IO–FTS is extended to that one of structured IO–FTS, since this allows to incorporate, in the definition of the stabilization problem, some amplitude constraints on the control input… (More)
— The problem of input–output finite-time stabilization of linear time-varying systems via dynamic output feedback is tackled in this paper. Sufficient conditions are provided in terms of Differential Linear Matrix Inequalities feasibility problems, which can be solved numerically in an efficient way by using off-the-shelf optimization tools, as illustrated… (More)
We report the results of the management of acute and acute-on-chronic slipped capital femoral epiphysis (SCFE) for 70 patients (81 hips) with an average follow-up of 6 years (range 1-15 years). We clinically reviewed 51 patients (55 hips) with acute or acute-on-chronic slip treated in our department from 1978 to 1993 with clinical and radiographic… (More)
—This paper introduces the extension of Finite-Time Stability (FTS) to the input-output case, namely the Input-Output FTS (IO-FTS). The main differences between classic IO stability and IO-FTS are that the latter involves signals defined over a finite time interval, does not necessarily require the inputs and outputs to belong to the same class of signals,… (More)
