Design Procedures of Some Interpolative Control Structures with Robustness Properties and Limitations

Abstract

The advantages using interpolative blocks in control structures are, mainly, based on
simplifying the solutions (easier implementation and reduced calculus time) and the possibility to
ensure for the control systems, in a relative easy way, some robustness properties. The goal of the
paper is to underline the possibilities offered by the interpolative-type control and to illustrate this
through a case study regarding to a positioning system. The case study suggests different issues
from which the problem can be viewed, from the control, robustness properties and also, from the
stability point of view, in Lyapunov' s acception.
