Nonlinear modelling and flatness-based control for electromagnetic reluctance force actuator

This paper presents an innovative compact high power linear electromagnetic multisensor actuator system, modelled and controlled using a non-linear control technique. Its target applications are those where high power, high bandwidth and accuracy of the response are the most important requirements. It presents a strong instability, due to the high power permanent magnets, that must be compensated by the nonlinear controller. In this paper are presented the modeling part as well as the design of the controller based on the differential flatness principles.
