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.
