Modal Sensors Placement Optimization

A new approach to optimal placement of sensors in modal sensor sense is presented. In contrast to existing methods, the optimal sensor set selection is based on suppressing of the observation of unwanted modes (typically higher order modes), while simultaneously the observability of low frequency modes should be as high as possible. An efficient numerical algorithm is presented, developed from an existing routine based on the Fischer information matrix analysis. Performance of our approach is demonstrated be means of two simple textbook examples.
