A digital sensorless velocity tracking controller for the permanent-magnet synchronous motor is presented. The control is sensorless in that it requires no mechanical sensors whatsoever, but instead uses a nonlinear observer to estimate rotor position and velocity from stator current measurements. Experimental results provide evidence of the viability and performance of the new control.
