摘　　要：调距桨快速启动,很容易造成负荷过载。针对调距桨系统的启动过程建模分析,研究出一种具有负荷限制功能的调距桨最佳启动算法。通过数学建模,计算机编程仿真,结果表明在一定的条件下,通过最佳启动算法可以得到较优的启动路径,使得主机能合理控制转速与螺距,在不超负荷状态下快速平稳地提高输出功率,很好地增强船舶启动过程中的机动性与灵活性。启动算法的研究对实际的船舶航行控制启动过程有重要的参考价值。Starting controllable pitch propeller quickly is likely to cause overloading. The controllable pitch propeller system is modeled. An optimal starting algorithm with load limit function of the controllable pitch propeller is developed. By mathematical modeling and computer programming simulation, the results show that under certain circumstance, an excellent startup path can be obtained. Starting the ship by the path can appropriately control the speed and pitch simultaneously, increase the power ouqmt smoothly, and enhance the ship maneuverability and flexibility. The research on starting algorithm is of great reference values to the startup process of the actual ship sailing.
