In an increasingly complex society, surrounded by an ircreasingly complex technology, the
need for general guidelines for the modelling of such complex systems is obvious. One of …

This chapter contains a discussion of conditions which must be met if a dynamical system is"
controlled" either in an" optimal" fashion or such that a trajectory of the system belongs to the …

This paper traces the evolution of the central concept of controllability of state space systems
introduced by Kalman to its behavioural generalisation byWillems, and beyond to distributed …

We take the position that 'complex'and 'simple'are not merely quantitatively different values
assigned to a single system attribute, measured by a numerical quantity varying over some …

During the last two decades or so, a new field of interdisciplinary research, often referred to
as the “science of complexity,” emerged from the interplay of physics, mathematics, biology …

The problem of stabilization of equilibria is one of the central issues in control. In addition to
its intrinsic interest, it represents a first step towards the solution of more complicated …

Complexity is generally viewed as an intrinsic property of certain kinds of systems, or at
least, as a property of a specific description of such systems. The view towards complexity …

Measures of complexity and meaning in nonlinear dynamical systems are presented,
applied to specific examples, and compared with each other. A basic conceptual and …
