Sensorless SPMSM Position Estimation Using Position Estimation Error Suppression Control and EKF in Wide Speed Range

Sensorless load and position estimation in linear reluctance actuator

Sensorless load and position estimation of linear reluctance actuator is investigated in this paper. Due to wide application of these actuators in several industrial automation systems, sensorless techniques are significant to decrease the cost of the system and increase the reliability in the closed-loop control systems. In this paper, based on dynamic model of the actuator and the characteris...

Sensorless Speed and Position Control of Induction Motor Drives

Controlled induction motor drives without mechanical speed sensors at the motor shaft have the attractions of low cost and high reliability. To replace the sensor, the information on the rotor speed is extracted from measured stator voltages and currents at the motor terminals. Vector controlled drives require estimating the magnitude and spatial orientation of the fundamental magnetic flux wav...
