Study on the improved topological index of distance matrix and its application;

The element of matrix in the distance matrix S*_~ij is defined and the topological index W* based on the distance matrix is defined as well.

According to the adjacency matrix and distance matrix of the two units, the sequential formulas to calculate Wiener topological indices or molecular topological indices have been given.

Based on the minimum matrix distance criterion, the method equals to aggregating individual pairwise judgment matrices to find a matrix, the sum of whose distances to the individual matrices is minimized, and then the latter reduces to a goal programming model.

By this ,this paper provide three training methods using weight matrix to emphasize the inherent differen.

It is the key technology for design of the constant beamwidth array to calculate the weight matrix.

A direct method to detecmine based on simple explicit relation among the optimal state feedback matix and the weighting matrices is proposed This method don′t need to do recursive calculation or complex transform for solving It is an effective approach to elminate the ″bottleneck″ problem that are caused by the application of LQ optimal theory to the engineerin

MPC solved a constrained convex quadratic optimization by defining reference trajectories, constraint limits, prediction horizon, control horizon and weighting matrices.

Based on the Hamiltonian system\'s theory,the relationship between closed-loop poles of system characteristic equation and weighting matrices was thoroughly investigated.

Approach to coordinate driving torque of redundant actuated parallel manipulator based on weighted matrix;

In order to make the designed linear meet the practical production requirement better,this paper represents the basic principle and design ways of LQR,introduces some choice rules of the weighted matrix Q and R.
