Virtual prototyping and system level optimization with VHDL-AMS application for the DTC control

This paper presents a VHDL-AMS description of a direct torque control (DTC) of an asynchronous machine and exposes some high-level-simulation results allowing a behavioral study with a virtual way. A DTC control is a multi-domain system including digital and analogue electronics power, an electrical motor and sensors. So that its simulation presents some difficulties. A VHDL-AMS description provides a good solution to solve this problem and permits to predict system performances when modifying its parameters.
