The interval based control: a new approach

Nonconventional control techniques (fuzzy logic control, neural control, numerical based fuzzy control etc.) have been fully used to implement automatic control of physical systems. In this paper, a novel nonconventional control technique, namely “interval based control”, is presented. The objective is the automatic control of physical systems represented by imprecise mathematical models. For the purpose of investigating the basic performance of the newly developed technique, one laboratory-scale plant was used, viz. a crane with two degrees of freedom. Experimental results, including a comparison with the conventional state variable feedback control technique, are also presented
