Abstract
The principal objective of this paper consists in
introducing the sliding mode control concepts in the speed’s
regulations control scheme of the induction machine powered by
static converters. The control by sliding mode is an interesting
technique for solving the problem of robustness of the
adjustment with respect to the variation of the load. So, the
control law in this technic is expressed mainly from the quantity
to be regulated and the number of derivatives. In practical
applications, the main disadvantage associated with the
command is the phenomenon of chattering. In order to minimize
the amplitude of oscillations, we propose a technique of variable
structure control which is softened several ramps control. In this
context, firstly, we will be introducing some general notions on
nonlinear systems as well as the design of sliding mode control.
Secondly, they will try to establish a methodology for designing
this control (conventional control and softened several ramps
control). Each stage of such study is illustrated and validated by
simulation results. Finally, we will be conducting robustness
testing to evaluate our order.
