On the basis of the conclusion above, the nonlinear weak controllable vectors can be obtained, which compose the second class of weak controllable matrix, by means of matrix transfermations of the first class of weak controllable matrix. Furthmore the second criterion of weak controllability, accessibility and strong accessibility, which is more standard, more succinct and more practical, is obtained. On the basis of the first criterion and the second criterion, several important problems about nonlinear controllability are discussed, which include 1 local controllability; 2 three classes of local controllable decomposition, separately by means of local coordinate changes in the neighborhood of a nonsingular point, a point on a singular surface or a designated point x〓 with a designated input u〓; 3 the character of controllability of the ith state variable x〓 in different controllable areas and their boundaries.

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.
