Description: 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 fixedpoint
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.
