Comparative Study of Conventional, Fuzzy Logic and Neural PID Speed Controllers with Torque Ripple Minimization for an Axial Magnetic Flux Switched Reluctance Motor

Abstract

Three speed controllers for an axial magnetic flux switched reluctance motor with only one stator, are described and experimentally tested. As it is known, when current pulses are imposed in their windings, high ripple torque is obtained. In order to reduce this ripple, a control strategy with modified current shapes is proposed. A workbench consisting of a machine prototype and the control system based on a microcontroller was built. These controllers were: a conventional PID, a fuzzy logic PID and a neural PID type. From experimental results, the effective reduction of the torque ripple was confirmed and the performance of the controllers was compared.

Axial flux switched reluctance machines: a comprehensive review of design and topologies

“…Generally, AFSRM designs are developed in power ranges from a few tenths [37,44,83] to several kilowatts [35,36,40,77,78,85,109,110] in various applications such as electrical transportation. But special designs like electrical trains are in the range of tens of kilowatts [43] or the applications related to laboratories are presented in the limited range of a few watts [88,111]. MEMS application is an exceptional case in which power is in micro-watt range; it is also the fastest and smallest AFSRM designed so far [46,47].…”
