Abstract
For structure protection and control, it is utmost to immediately detect the external force being imposed on the structure currently in civil engineering. In this thesis, we remodel the famous robust exact differentiator and tracking differentiator into a type of differential algebraic equations (DAEs), and then we solve the resultant DAEs by a Lie-group method, which can be used as an on-line estimator to detect unknown external force by using only a real-time measurement of the structural displacement under random noise in time. The estimated results obtained by the novel methods are quite promising.
