Abstract

This paper presents an improved FPGA based stator flux and torque estimators for direct torque control of induction motor drive. In voltage model -based of stator flux estimation, a low pass (LP) filter is normally used instead of a pure integrator to avoid integration drift problem due to DC off-set, noise and measurement error present in the back electromotive force (emf).In steady state condition, the LP filter estimator will degrade the performance and efficiency of the induction motor drive system since it introduced magnitude and phase errors. A simple method is proposed to improve the steady state performances of the drive system. MATLAB/SIMULINK and Xilinx System Generator tools are used to model and view the functionality of the proposed system.
