SVM-DTC System for PMSM Based on an Improved Sliding-mode Observer
Translated Abstract
An SVM-DTC system for PMSMbased on an improved sliding-mode observer is designed.SVM-DTC control method is adopted in the system to generate an expected voltage vector for the purpose of restraining the ripple of torque and flux linkage existing in conventional direct torque control.On the other hand,the Sigmoid function is used for quasi-sliding mode control over the sliding-mode speed observer,thus improving the conventional sliding-mode observer and realizing position-sensorless control in the SVM-DTC system.Simulation results have shown that this system can restrain the ripple of torque and flux linkage effectively and realize excellent speed observation.
