Abstract in Portuguese
Este trabalho desenvolve a simulação do controle de velocidade de motor de indução com a técnica de controle direto de torque (Direct Torque Control - DTC), sendo executada em um dispositivo lógico programável tipo FPGA (Field Programable Gate Array). A simulação é realizada usando-se dois programas: O MATLAB/Simulink e o ModelSim, sendo que estes dois programas trabalham em modo de co-simulação provida pelo toolbox Link-for-ModelSim do Simulink. Enquanto a dinâmica do motor e do inversor é executada no MATLAB, o algoritmo de controle da estratégia DTC é executada no ModelSim. O algoritmo de acionamento DTC é escrito em linguagem de descrição de hardware VHDL (Very High Speed Integrated Circuit Hardware Description Language - VHSIC HDL) e utiliza a aritmética de ponto flutuante. Os resultados das simulações são apresentados e analisados no final deste trabalho.

Abstract in English
This work presents a simulation of induction motor speed control using the technique of direct torque control (DTC), performed in a reprogrammable device type FPGA. The simulation is performed using two programs: MATLAB/Simulink and ModelSim, where these two programs work in a co-simulation mode, provide by Link for ModelSim toolbox from Simulink. While the motor and inverter dynamics is performed in MATLAB, the control algorithm of DTC technique runs in the ModelSim program. The algorithm of DTC drive is written in hardware description language (VHDL) and use the float point arithmetic. The simulation results are presented and analyzed in the end of this work.
