Abstract
Abstract This paper deals with constant or slowly variable disturbance reconstruction by means of extended observer for a multivariable system, namely an active magnetic suspension. Due to the nonlinear feature of the process, a cascaded continuous control scheme is first established. The structure of the model used in the high-level synthesis allows a decomposition in four simpler subsystems by means of a decoupling control law. Then an observer is built for disturbances and non measured state variables estimation. A digital control scheme is deduced using first order discretization of the continuous law. This paper ends with the presentation of experimental results that are obtained with a four degrees of freedom magnetic suspension controlled by means of a transputer specific board.
