Extensions in Symmetrical Optimum design method. Advantages, applications and perspectives

The paper deals with theoretical and applicative aspects concerning two extensions of the Symmetrical Optimum method (SO-m) for controller tuning in speed and position control of mechatronics systems. The methods, introduced by the authors and called Extended form of the Symmetrical Optimum method (ESO-m) and Double parameterization of the Symmetrical Optimum method (2p-SO-m), are briefly presented and some approaches regarding the methods are highlighted. Due to the applicability of the methods in the field of mechatronics applications (speed and positioning control of rapid plants), the presented aspects are of permanent actuality.
