An Intelligent Fuzzy PI Controller based 33 Level Switched Capacitor Multilevel Inverter for PMSM Drives

Abstract

This paper presents an intelligent Fuzzy PI controller based 33 level switched capacitor multilevel inverter for PMSM Drives and prove the advantages of proposed SCMLI. The traditional MLI topology indifferent viewpoint such as the number of required switches, power supplies, and output voltage levels are compared to this proposed topology. Further improving the speed response, torque ripple and anti interference ability PMSM and therefore a new fuzzy PI vector speed control method with adjustable proportion factor adjusted by RBF neural network has to be developed. The proposed design is implemented in MATLAB/Simulink and experimental results are given to confirm the better performance of proposed circuit.
