RESUMO

This work presents a hardware and software integrated environment for study and development of drivers and controls for induction motors. In the platform setup two Texas Instruments DSPs (Digital Signal Processors) has been used, in a master-slave conguration: the TMS320C6201 DSP, contained in a manufacturers evaluation board inserted in a PC, and the TMS320F240 DSP, in a board developed for the platform. Although two DSPs were used, it was sought to facilitate the use of the platform through the creation of functional blocks that can be manipulated in the Simulink software, very used in the companies and teaching institutions, as also through the Texas Instruments Code Composer Studio software, using the C language. The hardware of the platform has the necessary resources for rehearsals of induction motors, such as voltage, current, rotation and torque sensors, allowing the application of mechanical load through a controlled direct current motor. The induction motor is worked through an inversor, with PWM (Pulse Width Modulation) in strategy of Space Vector Modulation. The software levels and its interactions are described in the platform operation, so much in the slave board, as in the master board and in the PC. The forms of programming of the rehearsals and the sequence of procedures are presented for amplication of the existent resources. The rehearsals for O-line Identication of PWM Driven Induction Motors, and Vector Control of Induction Motors, demonstrate the power and exibility of the platform programming. The results indicate good performance of the platform for real time control systems applications . The platform has also the potential to serve as a tool in both teaching and developments of control and drivers techniques for induction motors in the Universidade do Estado de Santa Catarina (UDESC).
