An accurate estimation of dynamic loads and structural dynamic responses is deemed an indispensable prerequisite for developing trustworthy digital twin (DT) models of dynamically excited structures. Traditional joint load–response estimation (JLRE) algorithms necessitate a full-rank feedthrough matrix, implying that accelerometers are required at...
Structural health monitoring (SHM) has gained recognition in civil engineering and is now a well-established technique. Recently, it has received considerable research attention in the application in Wind turbine (WT) structures. A complete sensing system could provide comprehensive information about the structure during long-term operations. In th...
This paper presents a novel algorithm that reconstructs structural responses under unknown inputs and rank-deficient feedthrough matrix conditions. The algorithm eliminates one of the major constraints of existing filters (i.e., the requirement of a full-rank matrix), allowing the number of accelerometers required in real applications to be reduced...
Direct application of the Kalman filter algorithm to state estimation of civil structures presents a computational challenge due to their high dimensions and complexity. Rewriting dynamic equations using modal coordinates can be an alternative solution to this problem because high modes with minimal contributions to structural responses can be trun...
