Switched reluctance motor (SRM) drive has gained popularity in high-performance motion control applications where high speeds and soft torque are required. Nevertheless, presence of flux harmonics in the air gap results in unattractive torque ripples. The torque ripples deteriorate the performance of the high-performance drive applications. In this paper the speed of the SRM drive is controlled by using sensorless vector control. Flux in the motor is estimated by an estimator and the switching of the inverter is modulated by the vector control. To reduce the ripples in the torque, fuzzy logic controller is used. Rule based fuzzy controller is developed by considering error and change in error as inputs. The proposed system is validated by changing the load of the drive. Results obtained are found be acceptable and torque ripples are minimized significantly.

基于模糊逻辑控制器的开关磁阻电机无传感器矢量控制设计与开发

开关磁阻电机（SRM）驱动器已在需要高速和软扭矩的高性能运动控制应用中获得广泛应用。但是，气隙中存在谐波磁通会导致转矩波动不吸引人。转矩脉动会降低高性能驱动器应用程序的性能。在本文中，通过使用无传感器矢量控制来控制SRM驱动器的速度。电机中的磁通由估算器估算，逆变器的开关由矢量控制调制。为了减少转矩中的波动，使用了模糊逻辑控制器。通过考虑误差和误差变化作为输入来开发基于规则的模糊控制器。通过更改驱动器的负载可以验证提出的系统。
