Models for deterministic continuous-time nonlinear systems typically take the form of
ordinary differential equations. To utilize these models in practice invariably requires …

The purpose of this work is to show the real need to motivate theoretical research in
nonlinear digital control not only for solving control problems which are specific to the …

In this work sufficient conditions for uniform input‐to‐output stability and uniform input‐to‐
state stability are presented for finite‐dimensional systems under feedback control with zero …

It is shown that the formalism of asymptotic series expansions recently developed by the
authors for computing the solutions of non autonomous differential equations, can be …

This work deals with a sliding mode control scheme for discrete time nonlinear systems. The
control law synthesis problem is subdivided into a finite number of subproblems of lower …

This paper provides a formulation for using the delta-operator in the modelling of non-linear
systems. It is shown that a unique representation of a deterministic non-linear auto …

In this paper, a controller for induction motors is proposed. A continuous feedback is first
applied to obtain a discrete-time model in closed form. Then, on the basis of these exact …

We consider the Rayleigh beam equation and the Euler–Bernoulli beam equation with
pointwise feedback shear force and bending moment at the position ξ in a bounded domain …

In the present paper the problem of equivalence under coordinate changes and output
transformations to observer canonical forms is addressed in discrete time for multi-output …
