Abstract

This paper presents a fault tolerant control strategy for six-phase transverse flux tubular PMLM based on Synthetic Vector Method when the machine has a single phase open circuit fault. The operation of six-phase transverse flux tubular PMLM is described as well as its basic mathematical model. Then, the principles of Synthetic Vector Method are introduced. Based on these theories, the fault tolerant control strategy is derived in detail under the single phase open fault condition. In addition, a fault tolerant, dual Three-phase Four-leg Inverters drive topology which can be applied under this faulted condition is proposed. More, to implement the control algorithms proposed, a modified Space Vector Modulation is presented. Both the finite element simulation and the MATLAB/Simulink simulation results illustrate the validity of proposed fault tolerant control as well as the associated control topology and space vector modulation.
