Abstract
A novel structure of nonlinear integral backstepping
control has been proposed for induction motors. We can see
clearly that the structure of the controller generated by the
classical version of backstepping is composed of a proportional
action, which was added a derivative action on errors. Such a
structure makes the system sensitive to measurement noise. The
lack of integration means also the appearance of a constant static
error, caused mainly by non-zero mean disturbances. The
solution t o this p roblem i s to d esign a n ew v ersion of the
backstepping with integral action.
By using the proposed integral backstepping controller, the
system has a better load disturbance rejection capability. The
effectiveness of this proposed control structure is verified by
simulation as well as by experiment under critical disturbance
conditions.
