In this paper the use of a Reduced Order Extended Kalman Filter, to estimate the rotor position of a Permanent Magnet Synchronous Motor, in coordination with a Predictive Torque Controller is proposed. The observer integrates the information provided by the fundamental model and the anisotropies of the machine, allowing for a wide operation range. The scheme takes advantage of the nature of the predictive...
In the motion control of the sensorless permanent magnet synchronous motor system, the accurate detection of the rotor position at low or zero speed can improve control precision and enhance reliability. In this paper, a sliding mode observer is proposed based on the high frequency signal injection to estimate rotor position of the sensorless permanent magnet synchronous motor. Simulation results...
The application of the slide-mode observer in the sensorless vector-control of permanent magnet synchronous motor (PMSM) is proposed. Design a slide-mode observer to estimate the information of rotor position. Establish the adaptive rule and analysis the stability of the slide-mode observer. The application of the space vector pulse width modulation (SVPWM) is introduced in the control scheme of the...
The PMSM is inherently electronically controlled and requires rotor position information for proper drives. However, the problems of the space, cost, and reliability of rotor position sensors have motivated research in the area of position sensorless PMSM drives. Numerous rotor position sensorless control techniques have been proposed for PMSM drives, but most rely directly or indirectly on the estimation...
