Analytical modeling of multistack reluctance machines
Abstract
Although the multistack variable reluctance machine is a synchronous device, Park's transformation does not lead to a machine description with constant coefficients, or constant state variables during steady-state conditions. This complicates the machine analysis and makes linearization of the machine equations impossible. In this work, the method of dynamic multiple reference frames (DMRF) and a companion transformation are introduced which provide a model of the multistack variable reluctance machine in which rotor position dependent terms are not present and in which the state variables are constant in the steady state. The method whereby operating point stability may be determined using the DMRF models is set forth. The models are verified for both steady-state and transient conditions. Also, the DMRF technique is extended to the analysis of the unsymmetrical induction machine.
