**课程名称：** 无传感器开关磁阻电机控制技术 **课程概述：** 开关磁阻电机（SRM）是一种无需永磁体的变速驱动方案，具有宽温度范围、性能稳定、制造成本低、制造周期短以及高效率、紧凑尺寸等优点。其宽恒功率区域使其特别适用于电动汽车。全球对能源效率和紧凑型电机驱动的需求日益增长，也推动了SRM驱动市场的扩大。 然而，SRM无法直接使用交流或直流电源驱动，需要电力电子转换器配合精确的转子位置传感器来及时切换相励磁。这些位置传感器安装在电机轴上，会增加成本、体积并降低驱动器的可靠性。因此，为SRM驱动消除位置传感器的需求成为研究人员的重点关注对象。 本课程将深入探讨SRM驱动的无传感器控制技术基础。课程将详细介绍两种主流的无传感器控制基本原理：基于磁链的无传感器运行方法和基于电流斜率的无传感器方法。此外，课程还将解释其他几种无传感器控制技术的原理、优缺点及局限性。 **课程目标：** 本课程专为希望研究SRM驱动无传感器控制技术的科研人员设计。通过本课程，学员将能够： * 理解SRM驱动的基本无传感器控制技术。 * 获得修改现有无传感器方法或提出新方法的思路。
The Switched Reluctance Motor provides a magnetless solution for the variable speed drive which allows wider temperature variation without distorting the performance and also reduces the manufacturing cost as well as process time. It offers high efficiency in compact size. The wide constant power region makes it most suitable for the electric vehicle application. New trends in technology demand energy efficiency and compact electric motor drive all over the world which results in an increase in demand for the SRM drive.Unfortunately, SRM can not work with direct supply, neither with ac supply like Induction Motor, nor with dc supply like a DC Motor. It needs a power electronics converter with an accurate rotor positioning system to switch the phase excitation on time. These position sensors are mounted on the shaft of the motor which increases the cost and overall size of the motor and also reduces the reliability of the drive. Thus, to eliminate the requirement of position sensor from the SRM drive is becoming a prime interest of many researchers working in the development of the switched reluctance motor. This course covers fundamentals of the sensorless techniques of the SRM Drive.Numbers of sensorless techniques for the SRM drive have been published in the last decade. All the techniques use some basic principle of sensorless control and work around it with some modification according to requirements. This course covers two basic principles of the sensorless control techniques in detail. First is flux-linkage based sensorless operation and second is current gradient sensorless method. Working, advantages and limitations of several other sensorless control techniques are also explained in this course.This course is designed for the research scholar who wants to work on sensorless control techniques of the SRM Drive.This course will help understanding basic sensorless control techniques. It will also give ideas about how to modify or propose a new sensorless method.
