EXTREMAL TRANSFER FUNCTIONS IN ROBUST CONTROL SYSTEM DESIGN

Ľubomír Grman - Vojtech Veselý

   The paper addresses the design of a robust output feedback controller for SISO systems using extremal transfer functions and the classical control theory approach. It focuses on robust stabilization of uncertain plants which belong to linear or multilinear uncertain systems. A survey on extremal transfer functions is given and it is shown that for the proposed robust controller design procedure the classical linear control theory can be applied providing necessary and sufficient or sufficient stability conditions.

Keywords: robust control, extremal transfer function, interval control system and multilinear interval system
