Abstract:
|
This paper is concerned with the analysis of a singularity that can occur in three-dimensional
discontinuous feedback control systems. The singularity is the two-fold — a tangency of orbits to both
sides of a switching manifold. Particular attention is placed on the Teixeira singularity, which previous
literature suggests as a mechanism for dynamical transitions in this class of systems. We show that such
a singularity cannot occur in classical single-input single-output systems in the Lur’e form. It is, however,
a potentially dangerous phenomenon in multiple-input multiple-output switched control systems. The
theoretical derivation is illustrated by means of a representative example. |
