A new gain-scheduling sliding mode controller for permanent magnet synchronous motor (PMSM) was designed to achieve position tracing control and robust control. The sliding mode position controller is designed to ensure the tracing and robust performance of the PMSM servo system firstly, and then the gain-scheduling based on fuzzy logic theory is adopted to reduce chattering of sliding mode controller...
This paper proposes a novel high-performance rotor position estimator for an interior permanent magnet synchronous motor. By suitably processing the mathematical model of the motor, a systematic method of the rotor position estimating method has been developed. The proposed control system can be used in the space vector pulse-width-modulation switching method. By measuring the dc-bus voltage and the...
A control system for permanent magnet synchronous motor electric drives with a significant torsion vibration mode is presented based entirely on sliding mode principles to achieve robustness against external load torques and parametric modelling uncertainties in the motor and/or the driven mechanical load. The sliding mode control law respects the vector control condition by keeping the direct axis...
The control system for position control of the drive employing PMSM based on the principles of sliding mode control and respecting the principles of vector control is presented. Designed controller is chattering free and complies with demanded control precision. Described control technique divides PMSM into two channels, which enable to control motor flux and torque separately. The controller is of...
A novel control method for Permanent Magnet Synchronous Motor (PMSM) position servo systems is presented, which can greatly improve the dynamic performance of servo systems. In this method, the maximum reaching velocity control is introduced to reconstruct the conventional three closed-loop PID regulators. Under the new velocity and position control modes (two-segment modes), the PMSM servo systems...
