On-Board Voltage Regulation For All-Electric DC Ships

IFAC-PapersOnLine, 2018
Abstract In this paper, a control strategy is proposed for the voltage regulation and the shaft speed control of diesel generators on-board of all-electric ships with Direct Current (DC) power and propulsion systems. The proposed methodology is based on Input-Output Feedback Linearization (IOFL) of the prime mover dynamical model.
