Flatness, trajectories, and permanent magnet synchronous motor.


This paper describes the design, implementation, and control performances based on the flatness theory. Flatness is a tool which generates nominal controls to be applied to the system during transient. If the system model is well identified, then the synthesized control will be perfect. But, it’s necessary to add a feedback control to avoid the problems of model uncertainty, parameters variations and disturbance action. Thus, we associate an optimal regulator (LQR) to maintain the considered system outputs to their reference values.
