Abstract: |
In
this paper presents synthesis extended Gopinath
observer (EGO) and analyzes the asymptotic stability of a vector control
system for a squirrel-cage induction motor that contains in its loop an EGO.
The studied control system is based on the direct rotor flux orientation
method (DFCO) and the stability study is based upon the linearization theorem
around the equilibrium points of the control system, emphasizing the
estimated variation domain of the rotor resistance for which the control
system remains asymptotically stable when the prescribed speed of the control
system is close to zero. The stability study is made in continual case. The
mathematical model of the vector regulating system is made using a value linked
to stator current. |
