Speed Control of Permanent Magnet Synchronous Motor by Using Non-Linear SMC with Fuzzy- Logic Control

Author : Dr.K.Sri Kumar 1

Date of Publication :29th November 2017

Abstract: In functional Permanent magnet synchronous motor (PMSM) many uncertainties and disturbances exist which are both external or internal such as unpredicted dynamics, changes of parameters and interruptions in loads.The linear PI Controller technique is very tedious for restricting these disturbances. In turn, Sliding mode control (SMC) which is non-linear control method is adopted for improving the control performances and disturbance benefiting technique. A system which dynamically adjusts to the disturbances is being employed by SMC method based on one unique sliding-mode reaching law(SMRL),this will control chattering reduction input while maintaining high tracking performance of the controller. Then, for employing higher disturbances and obtaining servo precision, an extended sliding mode disturbance observer (ESMDO) is being proposed for assessing lumped uncertainties directly. A fuzzy sliding mode controller is used for reducing the disturbances during loading. Simulation and experimental results both show the validity of the proposed control approach.
