Abstract :
This work presents some considerations on a control method for a three-phase asynchronous motor and a time-frequency analysis of the proposed system. The control method uses the delta modulation principle to generate the command signals for a full bridge power inverter that drives three phase asynchronous motor. The time-frequency analysis can bring more new information that could be used to develop new control strategies. The operation principle and the analysis and simulation results are also presented to compare the performances of this control method versus a direct feed from mains
