The paper presents a novel control method based on a dual thread speed controller with modified multi-oscillatory control for speed ripple reduction in a switched reluctance machine-based drive. The method is based on on-line phase current shaping. The paper describes a dual thread angle-sampled multi-oscillatory control (ASMOSC) theory for speed ripple reduction of a switched reluctance machine under variable speed. Description of the entire cascaded speed control system with linear controllers is also provided, along with an implementation description for ASMOSC. This includes practical hints on how to apply the control system to a dual core microcontroller. The frequency-domain stability analysis for a designed control system under variable speed conditions is presented. The overall performance of the control system is verified numerically and experimentally on a laboratory setup with an 4-phase 8/6 SRM-based drive.
