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 switched capacitor 33 level multilevel inverter for PMSM Drives and the advantages of proposed SCMLI is proved. Compared to this suggested topology, the conventional MLI topology is compared with an indifferent viewpoint, such as the number of switches needed, output voltage levels and power supply. In order to further improve torque ripple, anti-interference capability and speed response, a new fuzzy PI vector speed control system with an adaptable proportion factor familiar by the RBF neural network must be created. The proposed design is implemented in MATLAB/ Simulink and the performance is improved for proposed circuit is achieved with experimental findings.
