摘要: In this short paper we present a discrete-time field oriented controller (FOC) for current-fed induction motors which insures global asymptotic speed regulation as well rotor flux norm tracking. To the best of our knowledge, is first time such result rigorously established implemented in discrete-time. insure stability condition on reference norm, time-varying, imposed. This disappears sampling period goes to zero, hence allowing independent and One important feature scheme that, compared with first-difference approximation classical indirect FOC, additional computational burden negligible. It also shown that can easily be extended case tracking time-varying references or position.
