A Novel High Performance Discrete Flux Integrator for Control Algorithms of Fast Rotating AC Machines

A Novel High Performance Discrete Flux Integrator for Control Algorithms of Fast Rotating AC Machines

This paper deals with the digital implementation of a motor control algorithm based on a unified machine model, thus usable with every traditional electric machine type (induction, brushless with interior permanent magnets, surface permanent magnets or pure reluctance). Starting from the machine equ...
