Sensorless Motor Drives with Predictive Current Control
Hardware complexity of a motor drive can be reduced by estimating controls rather than measuring using sensors. In this way the corresponding sensors are eliminated and the system becomes more robust. This article is about speed control of a sensor less induction motor with predictive current controller technique. This particular speed control technique does not require direct measurements of m...
متن کاملUsing an Appropriate Controller for Independent Current Control for Motoring of Force Windings of Bearing less Induction Motor
A bearingless induction machine has combined characteristics of induction motor and magnetic bearings. Therefore, the advantages are small size and low-cost. In the magnetic suspension of the bearingless motors, suspension forces are generated based on the feedback signals of displacement sensors detecting the movement of the rotor shaft. The suspension forces are generated taking an advantage ...

rotor field orientation stator field orientation stator model rotor model MRAS, observers, Kalman filter parasitic properties field angle estimation Abstract — 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 volt...
متن کاملTorque Control of Brushless Direct Current Motor Drives Using Single Current Sensor with High Reliability
Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...
متن کاملRobust method for stator current reconstruction from DC link in a sensorless induction motor drive
The electronic inverters normally operate in a current controlled mode. Current controllers are prone to errors associated with nonlinearity and offsets in the current transducers. Their successful operation requires measurement of the instantaneous values of stator currents. Using the switching signals and dc link current, this paper presents a new algorithm for the reconstruction of stator cu...
