Design of three moving massess missile system based on the fuzzy variable structure control;

Using of neural networks for the missile control system with moving masses;

And general nonlinear motion equations with three internal moving masses are provided.

A novel method of fuzzy proportional-integral-differential(PID) control by GA is designed for the attitude control system of three-axis-stable mass moment missile in this paper.

Based on the constructed model of mass moment control for missile, a coupled nonlinear dynamic system is presented by rational simplifying.

The gray level probability distributions of the mean square error and the mass moments and inertia moments of the column structures are obtained for the description of the formation and evolution of column structores.

The development of measuring instrument for the moment of mass of moving segment of human body;

By revising the rotation displacement equation,a mass matrix of this kind of structure is derived by virtual principle in this paper.

Revising the rotation displacement equation,the mass matrix and stiffness matrix of this kind of structure were derived by virtual principle.

In the thesis, the author calculates the natural vibration frequencies of several wide-span bridges by using lumped mass matrix and consistent mass matrix.

Influence of different quality matrix on natural vibration characteristic of bridges;
