A Rapid Prototype Design to Investigate the FPGA-Based DTC Strategy Applied to the Speed Control of Induction Motors

This work presents a virtual prototype for study and simulation of DTC technique applied to the speedy control of induction motor. The implementation is supposed to be realized in a FPGA device. The simulation was conducted using the Matlab/Simulink and the ModelSim programs. While the inverter/motor dynamics is executed in the Matlab, the ModelSim perform the speed control and the DTC procedure witch is written in VHDL-code. The both programs work in co-simulation mode provided by the Link-for-ModelSim toolbox in the Simulink. This virtual prototype was tested with the implementation of the DTC strategy using float point representation.
