The sensorless control of an axial flux permanent magnet motor drive is proposed and tested. The motor is not purposely designed for sensorless control and shows a very small inherent saliency. This significantly affects the saliency-based position estimation in the low speed region. Other nonidealities, such as the non-sinusoidal back-EMF waveforms and possible misalignment between stator and ...
متن کاملCurrent Control Strategy for the Sensorless Speed Control of Permanent Magnet Brushless Direct Current Motor
─ Brushless dc (BLDC) motor drives are continually gaining popularity in motion control applications. Therefore, it is necessary to have low cost, but effective speed/torque characteristics. A Brushless DC (BLDC) drives are known for higher efficiency and lower maintenance. As the name implies, BLDC motors do not use brushes for commutation instead, they are electronically commutated. For effec...
متن کاملRobust Control of a Speed Sensorless Permanent Magnet Synchronous Motor Drive
This paper presents the application of the Linear Quadretic Gaussian (LQG) controller to the state estimation and feedback of a speed sensorless permanent magnet synchronous motor (PMSM) drive system. The nonlinear model of the motor has been linearized on the basis of field orientation principle. The standard Kalman filter technique has been used to estimate the speed, position, and load torqu...
متن کاملDSP-Based Sensorless Speed Control of a Permanent Magnet Synchronous Motor using Sliding Mode Current Observer
Received Jan 30, 2014 Revised Mar 2, 2014 Accepted Mar 18, 2014 In this paper, experimental results of 3-phase permanent magnet synchronous motor (PMSM) sensorless speed control are presented. To estimate the rotor position, a sliding mode current observer (SMCO) was implemented. This observer estimates the back emfs of the motor in the stationary reference frame using only the measured voltage...
متن کاملMRAS Based Sensorless Control of Permanent Magnet Synchronous Motor
Speed and torque controls of permanent magnet synchronous motors are usually attained by the application of position and speed sensors. However, speed and position sensors require the additional mounting space, reduce the reliability in harsh environments and increase the cost of a motor. Therefore, many studies have been performed for the elimination of speed and position sensors. This paper i...
