✦ Synopsis

Proposed in this paper is a new approach of design using a monovariable generalized predictive control law, with multiple reference model (GPC/MRM) to control, "rstly, rotor speed and rotor #ux amplitude of an induction machine. The control law will be extended and applied, secondly, to answer a second objective which is the control of the rotor position and rotor #ux amplitude of the same machine. The non-linear dynamical model of the machine is described in the stator "xed reference frame. The GPC algorithm is combined with the non-linear input}output linearizing control properties; moreover, we establish a new formulation of the reference signals, which enables one to track #ux and speed/position nominal pro"les, satisfying motor constraints. The global controller synthesis is given under an RST form which introduces a novel de"nition of the pre"ltering polynomial.
