Adaptive control of permanent magnet synchronous motor with constrained reference current exploiting backstepping methodology

摘要

The presented paper proposes a novel control method of Permanent Magnet Synchronous Machine. Thanks to a recent technique called adaptive backstepping, adjustment of all motor parameters is obtained considering well known dq model. Furthermore, the introduction of a new trajectory generator gives the possibility to limit the reference current without breaking the adaptation process. Examples are calculated to illustrate the properties of the new control method.
