Abstract

This paper extends a family of techniques that recovers the physical parameters in a finite-element model of a structure with sensors or actuators spanning multiple degrees of freedom (DOF’s). Existing methods require each measurement to be associated with only one degree of freedom, each actuated degree of freedom can only be influenced by one actuator, and each actuator can only directly affect one degree of freedom. The extension presented here generalizes these methods to the case where each measurement can involve more than one degree of freedom, each actuated degree of freedom can be influenced by more than one actuator, or each actuator can directly affect more than one degree of freedom. A generalization of the concept of actuator and sensor collocation is developed in order to carry out the non-trivial extension.
