The Kalman filter has been shown to be ideally suited to both the state and parameter estimation problems in structural dynamics. However these exploratory works on the application of Kalman filtering to structural engineering problems, in general only give suboptimal results, relying on assumed statistics to describe the noise sequences. Optimality however can be achieved by adapting onto these statistics (or the filter gain), using output from the filter equations to feed the adaptive algorithm. The present paper details one recently developed adaptive approach which exhibits good computational and convergence properties. This is coupled with a correlation test to show the optimality or nonoptimality of the results in any given application. A seismically excited structure is used to illustrate the required problem formulation and estimation results. |
