The dynamics of the electric motors and generators (synchronous and induction) are highly nonlinear and content uncertainties including plant parameters variations magnetic saturation and external disturbances (load torque). On the other hand, the electric machine models are described by a class of nonlinear minimum phase systems which include the strict-feedback form or the nonlinear block controllable form (NBC-form) and stable residual stable. Therefore, in this case, to design a stabilized controller it is naturally to applied some feedback linearization (FL) technique: input-output (IO) linearization [9], backstepping (BS) [11] or block control (BC) ( [13]- [15]). It is interesting to note that the BC approach has some advantage comparing with the IO and BS ones.
