SOFT SWITCHING CONTROLLER USING DYNAMIC RULE SUBSETSFOR MULTIPHASE -MULTILEVEL INVERTER APPLICATIONS

Abstract

This work presents a Dynamic rule-based soft switching controller for multiphase multilevel inverter drives applications. The complete control scheme including dynamic rule based soft switching is simulated using Matlab/ Simulink package. Proposed Control activity is accomplished by starting measuring the significant parameters in a rule-based system and afterward deciding their membership grades in the proper subsets. Then the intersection point of the dynamic rule subsets associated with a given rule is found with the value of that intersection point. In this manner, the intersection point of every rule is determined. Finally, the net control action is found by consolidating the action indicated by each rule in extent to the related rule's intersection point. This procedure is delineated in the accompanying areas of this work. This is done to achieve high dynamic performance with low Total Harmonic Distortion (THD). The simulation results validate the proposed approaches.
