Abstract：The combined diesel-electric and gas turbine (CODLAG) system combines the advantages of electric propulsion system and mechanical propulsion system, so that it could meet the various needs of the voyage. A semi-physical simulation system is established to simulate the propulsion control strategy, and the propulsion work conditions are discussed and analyzed. First a propulsion control strategy, with the open-loop power control for both the gas turbine and the propulsion motor, is designed and achieved, and the operating characteristics on the main conditions are experimentally obtained. To accurately control the shaft speed, a new propulsion control strategy is proposed, where the close-loop control of shaft speed is used for the propulsion motor, and good characteristics are achieved. Results of experiments on two strategies are analyzed and compared to obtain the advantages and disadvantages of each control strategy, which could be used in the design of the propulsion control strategy for CODLAG ships.
