The definiens and working principle of controllable pitch propeller are introduced, the characters of CPP mechanism are summarized, and three types of shipping are concluded, which is applicable to equip with controllable pitch propeller by compared with pitch propeller. The control system of CPP usually adopts PID control, but the parameter of PID controller is adjusted inconveniently so as not to receive favorable result, therefore, the CPP control system based on fuzzy and neural network control is proposed so that improving the control effect. The result shows that the system design is feasible and effective.

介绍了可调螺距螺旋桨的定义及工作原理，并归纳了可调螺距螺旋桨推进装置的工作特性及特点，通过与定距桨进行的对比分析，总结出适用于可调螺距螺旋桨的三类船舶；目前调距桨控制系统一般采用传统的PID 控制方法，但由于PID控制器的参数不便于调节，不能取得良好的控制效果，从而提出了基于模糊神经网络控制的调距桨控制系统的设计，以提高调距桨在各种工况下的控制效果，仿真试验结果表明了调距桨控制系统设计的合理性。
