A modified optimal sensor placement method based on the effective independence method
(0) In this paper the effective independence method based on the Fisher information matrix is modified.Take capacity factor into account,deformation energy of specific stiffness is introduced to modify assignment matrix.Theoretical formula of the effective independence method、kinetic energy method and three estimating criteria were deduced.Then,with the background of a steel truss,the above optimal approaches were used for sensor placement and their effects were evaluated according to the three estimating criteria.Last,the results show that the modified effective independence method is better than the others methods above,it can reflect structural character better.
