Hopf bifurcation in indirect field-oriented control of induction motors

  title={Hopf bifurcation in indirect field-oriented control of induction motors},
  author={Francisco Gordillo and Francisco Salas and Romeo Ortega and Javier Aracil},
The appearance of self-sustained oscillations in high performance AC drives, and in particular, in induction motors whose speed is regulated with the industry standard "eld-oriented control, is a well-documented but little understood phenomenon. It is well known that the oscillations may be quenched by returning the outer-loop PI speed control, but no precise rules to carry out this task, which may be time consuming, are known. In this paper, we show that these oscillations may arise due to the… CONTINUE READING
