Abstract:

This study designs and implements a Modular Multilevel Inverter (MMI) to intelligently regulate the Induction Motor (IM) drive for maritime water pumping. An eleven-level inverter can adjust the speed of a solar-powered IM drive.

Pumping techniques aboard ships use roughly 50% of the overall energy. This research analyzes and tests a simplified control architecture for a maritime water pumping system using an induction motor (IM) drive and MMI. Improved inverter performance is achieved by Proportional-Integral (PI) and Fuzzy Logic (FL) controller analysis.

Better robustness in peak overshoot, controller settling time, and inverter THD was compared. Simulations are done in MATLAB/Simulink and experimental implementation is done with FPGA.

Results are used to examine controller performance, better inverter output voltage, reliable induction motor speed control, and harmonic reduction to improve power quality. The suggested control technique integrates MMI, IM drive, and intelligent controller exclusively for marine water pumping, making it new.
