RESUMO

This work has the aim of making the performance evaluation of a new open loop speed control method based on the scalar V/f technique for induction motors. The proposed system has been designed intending to minimize speed error through the introduction of the following compensation techniques: Voltage compensation based on the phasor analysis of the input variables; frequency compensation design took into consideration the non-linear relationship between torque and slip frequency; and slip estimation pondering magnetic losses on the determination of the air-gap power. The system has been implemented using a Digital Signal Processor (DSP). Through the obtained results of the implemented system and the issues that were discussed on this dissertation, the advantages as well as the limitations of this method for many driving conditions as well as the applicability of it in industrial systems were identified.
