Firstly, the mathematical model of marine engine speed regulation system is established based on the analysis of the operation of a marine engine. Then, with the consideration of low efficiency of marine engine speed regulation process due to the complexity of its operational condition, both PI control algorithm and adaptive control algorithm are designed for improvement of the speed regulation process. The adaptive control algorithm adopts self-organizing through modification of weighted values come from correlative search, as well as a coefficient of smoothness is adopted to smooth the modification process of weighted values. Finally, simulation experiments of speed regulation process under the application of the abovementioned two different control algorithm are fulfilled and related experimental results are compared. The results show that the designed adaptive control algorithm is with better properties for speed regulation of marine engine.
