M. Hari Prabbu

Abstract :

This paper is based on the reduction of oscillation, and robustness. However, due to the control rule base, the closed loop control of Switched Reluctance Motor drives using Z–Source Inverter with the modified rule base of 5x5 using Fuzzy Logic Con froller(FLC) with the output scaling factor(SFself–tuning mechanism are proposed. The aim of this paper is to simplify the program complexity of the controller by reducing the number of fuzzy sets of the membership fun ctions(MFs) without losing the system performance and stability via the adjustable controller gain.ZSI exhibits both voltage–buck and voltage–boost capability. It reduces line harm onics, improves reliability, and extends output voltage range.The output SF of the controller can be tuned continuously by a gain updating factor, whose value is derived from fuzzy logic,with the plant error and error change ratio as input variables. Then the expected results,carried out on a four–phase 6/8 pole SRM based on the dSPAC’EDS11O4 platform, to show the feasibility and effectiveness of the devised methods and also performance of the proposed controllers will be compared with conventional counterpart.
