stator resistance estimation in direct vector control for high performance torque controlled induction motor drives
sensorless speed torque control of induction machines has been widely used in many industrial applications. the simple method of direct vector control can provide tacholess control as well as more complex approaches. in this method, the motor flux can be obtained by measuring voltage and current and integrating motor back electromotive force. the only required motor parameter is stator resistan...
متن کاملA Stator Resistance Estimation Scheme for Speed Sensorless Rotor Flux Oriented Induction Motor Drives
− Accurate knowledge of stator resistance is of utmost importance for correct operation of a number of speed sensorless induction motor control schemes in the low speed region. Since stator resistance inevitably varies with operating conditions, stable and accurate operation at near-zero speed requires an appropriate on-line identification algorithm for the stator resistance. The paper proposes...
متن کاملInduction Motor Speed Control Using Fuzzy Sliding Mode Controller Based on Direct Field Oriented Control
This paper discusses fuzzy sliding mode controller applied for induction motor field oriented control with space-vector pulse-width modulated inverter. The speed control is obtained by controlling the inverter switching frequency determined by the reference voltage resulted by the controller. Simulation results show that fuzzy sliding mode controller performed satisfactorily and better compared...
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 ...
متن کاملFuzzy Direct Torque-controlled Induction Motor Drives for Traction with Neural Compensation of Stator Resistance
In this chapter, a new method for stator resistance compensation in direct torque control (DTC) drives, based on neural networks, is presented. The estimation of electromagnetic torque and stator flux linkages using the measured stator voltages and currents is crucial to the success of DTC drives. The estimation is dependent only on one machine parame‐ ter, which is the stator resistance. Chang...
