This paper presents the sensorless speed control of 6/4 pole SRM drive based on hybrid observer (HO). It consists of two modes, i.e., current sliding mode observer is for high speed and flux linkage sliding mode observer is for low speed control. A nonlinear model of SRM is simulated in MATLAB/Simulink. HO is simulated from low to high speed level, and also estimated position and speed errors are optimized with ANFIS and fuzzy-PID methods. Experimental validation is taken for three set speeds, and measured results are compared with the simulated results. Overall speed and position estimated error, electromagnetic torque ripple output results are compared, and its values are tabulated at the end. This observer has the advantages of high-precision speed control without any additional hardware, and also performance has improved.

使用 ANFIS 和基于模糊 PID 的混合观测器对 6/4 极开关磁阻电机进行无传感器速度控制

本文介绍了基于混合观测器 (HO) 的 6/4 极 SRM 驱动器的无传感器速度控制。它由两种模式组成，即电流滑模观测器用于高速控制，磁链滑模观测器用于低速控制。在 MATLAB/Simulink 中模拟 SRM 的非线性模型。从低速到高速模拟 HO，并且还使用 ANFIS 和模糊 PID 方法对估计的位置和速度误差进行了优化。对三种设定速度进行实验验证，并将测量结果与模拟结果进行比较。将整体速度和位置估计误差、电磁转矩脉动输出结果进行比较，其数值在最后进行了列表。该观测器具有无需任何额外硬件即可实现高精度速度控制的优点，并且性能也有所提高。
