چکیده
This paper presents to obtain the state estimations in low speed induction motor using Sensorless Constant Switching Frequency Controller (CSFC) technique. The state estimations referred to flux and torque. Therefore the CSFC enabling Induction motor with Direct Torque Control is built using the MATLAB/SIMULINK. The switching frequency is maintained constant in order to improve its state estimation with smaller sampling period. Keywords— Induction motor (IM), Direct Torque Control (DTC), Constant Switching Frequency Controller (CSFC), Flux estimation, Torque estimation.
