Optimal Sensor Placement for Structural Health Monitoring: A Comparative Study between the Control Engineering and Civil Engineering Approaches

摘要

We conduct a comparative study of approaches for optimal sensor placement from the fields of control engineering and civil engineering. The widely used civil engineering approaches such as EI and MAC have limitations due to the negligence of damping parameters. On the other hand, control engineering approaches do not consider the key parameters of interest in civil structures. We study the maximization of estimation performance of key structural characteristics from impulse response data, using approaches from both fields to unveil the pros and cons of each.
