Arithmetic and implementing on indirect position detecting of SRM based on FPGA

Flux-linkage calculation and arithmetic on switched reluctance motor are discussed and a way to simplify the computation of flux-linkage with trapezoidal integration form is analyzed. Design and implementing of arithmetic and control for SMR position detecting with FPGA technique are presented. The design which has the merits of small memory space to use and fast speed to realize is proved correct, effective and practical and has great value to be extended.
