A lot of distributed systems have a transfer function which is rational in the variables s and
e− θs. Effective procedures for their control are based on the factorization of the transfer …

A trajectory tracking control method for a class of non-linear systems with time delays is
proposed. For this, the new concept of delta-flatness is introduced, which is an extension of …

This paper provides an overview of recent results for relay-delay systems. In a first section,
simple examples illustrate the problems induced by delays in the synthesis of sliding mode …

In this paper, we consider the problem of assigning, by state feedback, a finite spectrum to a
single-input system with commensurate point delays. It is well-known that spectral …

Flatness based analysis and closed loop control design for networks of hyperbolic pde's is
considered. To this end a state space description is assigned to the flatness based …

We discuss controllability of systems that are initially given by boundary coupled PDEs of
second order. These systems may be described by modules over particular rings of …

Pole placement represents a classical method for controlling finite-dimensional linear time-
invariant systems, largely covered in the open literature. Basically, it consists of placing the …

A flatness based approach to the analysis of state controllability of systems described by one
or more boundary coupled 1D hyperbolic second order equations is proposed. To this end …

One dimensional boundary value problems with lumped controls are considered. Such
systems can be modeled as modules over a ring of Beurling ultradistributions with compact …

The use of distributed delays in the control law of time-delay systems has been proposed by
several authors. The implementation of such controllers is not trivial, and recent publication …
