The present paper deals with the development of a Quasi-Sliding-Mode control scheme, suitable for position and speed regulation of electric servodrives, using a novel Fuzzy Logic approach. The new control scheme solves some of the major drawbacks of Sliding Mode controllers such as the excessive energy needed in control and chattering. Such new control scheme maintains the traditional simplicity and robustness of Sliding-Mode controllers. A practical comparison between the new control scheme and conventional Sliding-Mode and Fuzzy equivalent PI techniques is also reported in the paper, confirming that the proposed approach is effective and works better either at steady state and during transients.

Abstract
The present paper deals with the development of a Quasi-Sliding-Mode control scheme, suitable for position and speed regulation of electric servodrives, using a novel Fuzzy Logic approach. The new control scheme solves some of the major drawbacks of Sliding Mode controllers such as the excessive energy needed in control and chattering. Such new control scheme maintains the traditional simplicity and robustness of Sliding-Mode controllers. A practical comparison between the new control scheme and conventional Sliding-Mode and Fuzzy equivalent PI techniques is also reported in the paper, confirming that the proposed approach is effective and works better either at steady state and during transients.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
