Method of Applying Force Distribution Function for Linear Switched Reluctance Motor Driven by Current Source Inverter

This paper presents a thrust ripple reduction method for a linear switched reluctance motor (LSRM) driven by a current source inverter (CSI). For thrust ripple reduction, a control method using a force distribution function (FDF) is applied. A new circuit configuration is proposed in order to apply the FDF to the LSRM driving system with the CSI. Performances of the LSRM with the proposed driving system are investigated by a dynamic simulation and experiments. As a result, it was confirmed that the thrust ripple reduction method using the FDF could be applied to the LSRM driven by the CSI.
