Minimal Time Output Deadbeat Control with Internal Stability

Output deadbeat control of nonlinear discrete-time systems with one-dimensional zero dynamics: global stability conditions

Output deadbeat control in one step is considered for a class of discrete-time systems described by a nonlinear single-input/singleoutput recursive representation. Global stability conditions are established for the particular subclass of systems with one-dimensional zero dynamics. The results are illustrated with applications to polynomial and neural dynamical systems.

Absolute Stability of Single-Input Single-Output Systems with Constant Internal Point Time Delays

Abstract. This paper deals with the absolute stability of single-input single-output time-delay systems with, in general, a finite number of non commensurate constant internal point delays for any nonlinearity satisfying a time positivity inequality related to the first and third quadrants. The results are obtained based on Lyapunov’s stability analysis via appropriate Lyapunov’s functions and ...

Input-Output Finite-Time Stability

This paper introduces the extension of FiniteTime 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, and that quantitative bounds on both inp...

Multivariable Ripple-Free Deadbeat Control

The design of multivariable ripple-free deadbeat controllers is a complex task. One approach which has shown promise for solving multivariable ripple-free deadbeat control (MRFDC) problems is the use of Diophantine equation parameters. The problem of solving robust multivariable ripple free deadbeat with time delays has not been solved. This paper proposes a hybrid two degree of freedom control...
