Abstract	Marine exhaust gas turbo-generation system is a kind of supplemental generation system used in ocean ship which contributes to improve the recovery ratio of thermal energy carried away by exhaust gas produced by ship main engine to save energy. Firstly, the operation principle of exhaust gas turbo-generation system is analysed. And the simplified mathematical models according to the main components of the generation system are established respectively using method of linearization and reduction of order. Based on the models of the concerned components of the generation system, the model of the whole generation system is established corresponding to the interaction of demanded active power and shaft rotation speed of generator. Secondly, an adaptive control method is designed to substitute for the proportional-integral (PI) control method of rotation speed regulation of the exhaust gas turbo-generator. According to the algorithm of the control method, the control system makes self-organizing through modification of its weighted values, and the weighted values are determined through correlative search. Additionally, a smoothness factor is applied during the modification of the weighted values, which makes the procedure of the weighted value modification more smoothly. The experimental result shows that, when the rotation speed regulation process of the exhaust gas turbo-generator is concerned, its dynamic property under the adaptive control is better than that under the PI control. And the designed adaptive control method is proved to be more suitable for the control of rotation speed regulation of marine exhaust gas turbo-generator than the traditional PI control method.
