| Abstract |
Predictive algorithms are proposed for direct torque-control of synchronous permanent magnet drives. Reference is made to microprocessor-based control systems. By means of a suitable formulation of the machine mathematical model and on the basis of some measured quantities, the average motor torque is evaluated for each sampling interval in correspondence of all the possible inverter modes. The control algorithm selects the states able to yield the minimum deviation between the predicted electromagnetic torque and the reference one. Advantages and limitations of the control strategy are highlighted through the analysis of simulation results in comparison with the ones obtained by using other techniques.
Sorne heavy transient operations are investigated and compared. |
