Abstract
This paper develops a Sobol sensitivity analysis model of thrust force of linear switched reluctance motors (LSRMs), to quantitatively analyze the coupled influence of parameters on the thrust force ripple. A nonlinear thrust force model of a developed LSRM is first given. Using Sobol sensitivity analysis method, the local and global sensitivity indexes are deduced according to thrust force model. In addition, applying the deduced sensitivity indexes, local and global sensitivity results of thrust force are obtained, and the quantitatively coupled influence of parameters on the thrust force ripple is presented and analyzed.
