Abstract :
An orthogonal scheme that can be applied to the control of a linear switched-reluctance motor (LSRM) is presented. By using this scheme, the motor reluctance forces, which are magnetically decoupled and position dependent, can be projected onto sets of stationary axes that are aligned with the motor fixed secondary poles. Hence the electromagnetic forces can be designed not only for driving the LSRM at its propulsive direction but also for alleviating the load at its normal direction. Consequently, the LSRM will be quite applicable for the desired operations of a magnetically levitated vehicle. A detailed algorithm and experimental results are provided to show the validity of the proposed scheme
