A robust fuzzy logic based control system is proposed to control the speed of electrical servo drives in this paper. A novel speed controller is designed using the concept of fuzzy logic, which ensures robust speed control against parameter variations. A fuzzy logic control is implemented for permanent magnet synchronous motor (PMSM) servo drive. Heuristic knowledge is applied to define fuzzy membership...
The paper deals with the problem of robust speed control of electrical servodrives. A robust controller is developed using a nonlinear IP controller. The controller nonlinear characteristic is obtained due to fuzzy logic technique application. An original method of controller settings adjustment is presented. The use of this adjustment procedure ensures robust speed control against the variations...
A sliding mode variable structure control (SMVSC) method based on fuzzy self-learning for a direct-drive AC linear servo system is presented. SMVSC is a special nonlinear control strategy, which has strong robustness against parameter variations, load disturbances and uncertainty of system. This paper proposes that the chattering can be effectively minimized by introducing fuzzy self-learning in conventional...
