Abstract

© 2018 IEEE. This paper presents a new Direct Instantaneous Torque Control (DITC) developed to minimize the inherent torque ripple of an aerospace switched reluctance motor (SRM). In addition to good performance, the reliability and robustness of the overall system are of great concern in aerospace and other safety-critical applications. By taking that into consideration, a DITC, that is less prone to the common erroneous operating conditions associated with SRM control such as measurement errors and noise, integration errors and parameter variation errors, is developed and compared with the traditional current chopping control (CCC). The proposed control scheme involves simple torque estimation, distribution, and regulation strategies. The results obtained show that both the proposed DITC and the traditional CCC methods ensure accurate reference tracking. However, the proposed control exhibits better torque ripple reduction capability without compromising the system's reliability and robustness.
