ABSTRACT
The paper discusses discrete control systems of interval plants, corresponding to a certain plants family, the parameters of which belong to the given sets. It is shown that the use of internal nominal model having the impulse characteristics of finite prolongation allows to build a robust nominal system, the properties of which are nonsensitive (or,weakly sensitive) to the external and parametric disturbances that affect the plant. In the similar systems the restrictions that are caused by the high order, nonminimum phase and variable–in–time parameters of plant, being controlled are taken away. Robust nominal systems are compared with traditional adaptive systems.
