High performance tracking of linear synchronous reluctance servodrive

The paper deals with the design of high performance tracking control of the linear synchronous reluctance motor (LSRM). The control design procedure is based on the nonlinear dynamic LSRM model. The input-output linearization is used to obtain the linearized model of the LSRM model, which is then stabilized by the linear tracking controllers. Input-output linearizing control combined with the tracking controllers provides good tracking performances and high disturbance rejection of a servodrive. The translation range of the tested LSRM is limited, therefore the position speed and acceleration trajectories are calculated from the kinematic model. The performances of the proposed input-output linearizing control are compared with the performances obtained by the classical cascade control. The comparison of the results has shown that the proposed input-output linearizing control provides much better performances than the classical cascade control.
