Resumo: | Until a few decades, control systems for induction engines (totally more robust than the other kind of engines) were more costly when compared with the control of motors of continuous current. With the advent of theory of vector control and the technological development of semiconductors this context has altered itself, nearly matching the characteristics of the induction and continous current motors. This work will present the implementation of a system for the vector control for the imposition of currents control for the trifase induction. The system was developed through a microcomputer, a system of data acquisition, a rectifying bridge with diodes and an inverter bridge with IGBTs with drivers for pivoting. A theoretical introduction will be presented about vector control, where a control loop will be shown that has been proposed for Leonard (1986) in which the control was based. Following this the presentation of the software and hardware developed through the hystherisis of current, will impose the current to the motor. Finally the results obtained will be seen, showing the speed control of the motor with load variations, including with the inversion of rotation of the same. |
