Sensor less Speed Control of 8/6 Switched Reluctance Motor Drive via Hybrid Observer Using ANFIS and Fuzzy-PID

Abstract

This paper presents the Speed control of 8/6 Switched Reluctance Motor (SRM) using Adaptive Network-based Fuzzy Inference System (ANFIS) and Fuzzy-PID with Hybrid Observer (HO) algorithm. The hybrid observer (HO) algorithm gives the optimum value of estimated position angle and speeds are taken with the combination of Current Sliding Mode Observer (CSMO) and Flux Sliding Mode Observer (FSMO). The non linear model of 8/6 SRM is modeled with MATLAB Simulink and the parameters of Actual speed ,Estimated speed ,Error of speed and Torque ripples are measured correspondingly. The results of ANFIS and FUZZY-PID are compared with wide ranges of speed and the same is presented. The experiments are carried out on a four-phase 8/6 SRM using DSP TMS320LF2407A platform; it shows the achievability and significance of the developed methods for low, medium and high speed operations.
