Speed control system with variable structure and Fuzzy-adaptation, insensitive to changes in parameters.

Abstract

The use of Fuzzy-logic in the field of electric drive control systems with a switching structure is described. Fuzzy-logic is applied in order to improve the operation of electric drive systems with a switching structure when changing parameters. A Fuzzy adapter is proposed, which uses as the information for switching the structure a linear combination of error and its derivative, as well as a derivative of this combination. The results of the drive simulation with the variation of the moment of inertia over a wide range are presented.
