FPGA Based Torque and Flux Estimator of Direct Torque Control for Induction Machine Drives
ABSTRACT: This paper presents
a new design of the torque and stator flux estimators for Direct Torque control
(DTC) for Field Programmable Gate Array (FPGA) implementation, which permit
very fast calculations.An alternative variable word-size approach in two’s
complement fixed-point format is used for the implementation, in order to
minimize calculation errors and the hardware resource usage. The simulation
results of DTC model in Matlab, which performed double-precision calculations,
are used as references to digital computations executed in FPGA
implementation.The Hardware-in-the-loop (HIL) method is used to verify the
minimal error between Matlab simulation and the experimental results, and thus
the well-functionality of the implemented estimators.
