【Abstract】 The rotor velocity and position can be taken as two states variable of the system by using the extended kalman filter, which based on the theory of the brushless dc motor. Based on the measured stator currents and stator voltages, we can estimate the rotor velocity and position. It is very useful for us to study the application of the velocity and position sensorless operation of brushless DC motor drives.更多还原
