An Overview of Advanced Control Technologies for Marine Propulsion Motors
By
Progress In Electromagnetics Research B, Vol. 116, 138-157, 2026
Abstract
With the ongoing transformation of the global energy structure and the growing demand for environmental sustainability, transportation electrification has been rapidly advancing and is becoming a key pathway toward achieving carbon neutrality. Maritime transportation accounts for a significant share of carbon emissions, where conventional fuel-based propulsion remains dominant. Consequently, marine electrification is experiencing a transformative opportunity driven by both energy and environmental imperatives. As the core component of the propulsion system, the electric motor places increasingly stringent requirements on control performance and reliability. This paper reviews recent advances in marine propulsion motor control technologies, focusing on three major areas: model predictive control (MPC), fault-tolerant control (FTC), and position sensorless control. In MPC, multi-plane modeling and virtual voltage vector regulation for six-phase permanent magnet machines have substantially improved dynamic response and control accuracy. Additionally, multi-objective optimization can be achieved through the design of weight factors, while the introduction of observers or data-driven approaches can enhance robustness against parameter variations. In FTC, the development from optimal current compensation to post-fault subspace reconstruction topologies has provided a theoretical foundation for robust control under complex operating conditions. In position sensorless control, medium- and high-speed sliding-mode observation combined with low-speed high-frequency signal injection enables accurate position estimation over the full speed range. Future research is expected to integrate the feature extraction and modeling capabilities of machine learning to enhance observer design and fault-tolerant strategies, promoting the intelligent and data-driven evolution of marine propulsion motor control technologies.
