Abstract Switched reluctance motors (SRMs) are used in the industry due to their simple motor design construction, the susceptibility of running at wide speed range, high torque to inertia ratio, low cost, and high reliability. In this paper, the SRM drive system is fed from asymmetric four-phase power converter (APC) using soft switching technique. This paper presents a proposed precise speed controller (PSC) for a four-phase 75 KW 8/6 SRM. The performance of the PSC is evaluated and compared with PI and fuzzy logic (FLC) speed controllers. This comparison is based on the values of the rise time, settling time, overshoot, undershoot, speed error in the steady state, and torque ripples percentage of the three speed controllers. The robustness of the proposed PSC is validated in such cases e.g. mechanical parameter disparities, and external load disturbances. The four-phase SRM responses of motor speed versus speed command, speed error, four-phase currents, SRM reference current, and electromagnetic torque are investigated using MATLAB/SIMULINK.

非对称功率变换器馈电的四相开关磁阻电机的高精度调速

摘要 开关磁阻电机(SRM)由于其电机设计结构简单、易于在较宽的速度范围内运行、高转矩惯量比、低成本和高可靠性而在工业中得到广泛应用。在本文中,SRM 驱动系统由使用软开关技术的非对称四相功率转换器 (APC) 供电。本文提出了一种用于四相 75 KW 8/6 SRM 的精确速度控制器 (PSC)。评估 PSC 的性能并与 PI 和模糊逻辑 (FLC) 速度控制器进行比较。这种比较是基于三个速度控制器的上升时间、稳定时间、过冲、下冲、稳态速度误差和转矩脉动百分比的值。提议的 PSC 的稳健性在这种情况下得到验证,例如机械参数差异,和外部负载干扰。使用 MATLAB/SIMULINK 研究了电机速度与速度指令、速度误差、四相电流、SRM 参考电流和电磁转矩的四相 SRM 响应。
