A Tutorial to Implement a BLDC Motor Speed Control for an Electric Boat Using Simscape and Simulink

The marine sector is moving towards all-electric ships to improve energy efficiency and reduce air pollution. A key part of an electric propulsion system for an electric ship is the electric motor, especially permanent magnet motors, known for their high torque and efficiency. Recently, brushless DC (BLDC) permanent magnet motors have rapidly advanced, matching the pace of electric boat development. These motors are preferred for their efficiency, reliability, and low maintenance, making them suitable for varying water conditions. Despite much research on BLDC motor modeling, there are few tutorial-style guides. This paper offers a step-by-step tutorial for using Simscape and Simulink to control BLDC motors in electric boats. The simulation results demonstrate excellent speed tracking, closely matching the desired speed without overshooting. The system swiftly adjusts to rapid speed changes during acceleration and deceleration, which is essential for applications requiring quick adjustments. This guide helps engineers and researchers design, test, and optimize motor control systems, promoting efficient and sustainable electric boating solutions.
