To avoid large amounts of computation of the traditional generalized predictive control algorithm, a fast algorithm of GPC based on implicit generalized predictive control and the soft coefficient matrix is presented by exactly computing the current control action and approximately computing the future control sequence off line.

Damage identification of main girders for long span cable-stayed bridge based on flexibility matrix;

Study indicates that flexibility matrix is a kind of powerful method of structure damage detection.

The explicit unified expression of element compliance matrix and the explicit formulations for the displacements of element nodes are derived from the concept of base forces.

The process of elastohydrodynamic analysis combined with compliance matrix was described,and an elastohydrodynamic calculation was done using ORBIT as tools with compliance matrix on conrod big-end bearing of a 4 cylinder in-line diesel engine.

An explicit expression of element compliance matrix of the finite element method for arbitrary meshes is derived using the base forces.

A method of flexibility matrix H diagonalization for constructing hybrid stress finite elements;

In this paper,based on the simulation analysis of continuous box girder bridge,comparative analysis of curvature mode method and flexibility matrix method is studied on three aspects of sensitivity on damage detection,accuracy on detection and localization and anti-influence of test error.
