In electrical drives using an actuator supplied by a static converter, it is possible to work out a model of the converter-motor system which is easily implemented on a hybrid or digital computer. This model can be elaborated to improve the efficiency of the digital simulation. Computation time...

The measurement of the rotation speed is an important issue in closed-loop industrial drives. The motor speed is often calculated by a derivative operation of the position measure obtained by an electromagnetic resolver. As a consequence, especially at the lowest speeds, the noise overlapped to...
