Nonlinear decoupling of an induction motor drive with input filter

In this paper, the nonlinear decoupling control of a high power induction motor with input filter is investigated. Keeping a field-oriented control structure, the decoupling terms are modified so that the physical characteristics of the plant can be taken into consideration. Finally, in order to separate the problems of input filter instability and induction motor control, a decoupled supply voltage control is presented.
