Abstract : Control of Induction Motor (IM) is well known to be
difficult owing to the fact the models of IM are highly nonlinear
and time variant. In this paper, to achieve accurate control
performance of speed control of IM, a novel method is proposed
by using adaptive inverse control (AIC) technique. AIC is
actually an open loop control scheme and so in the AIC the
instability problem cased by feedback control is avoided and the
better dynamic performances can also be achieved. The model of
IM is identified using adaptive filter as well as the inverse model
of the IM, which was used as a controller. The significant of
using the inverse of the IM dynamic as a controller is to makes
the IM output response to converge to the reference (desired)
input signal. To validate the performances of the proposed new
control scheme, we provided a series of simulation results.
