Abstract: The
class of system considered is a single degree of freedom undamped vibrating system with a clearance in which the
dynamical behavior is described by a state-space representation
in real time. The direct identification technique for the
estimate of a clearance and other parameters in the system is
presented in terms of least squares method and step-by-step
iteration approach. For numerical simulation purpose, the
simulated data are achieved by corrupting the modeled responses.
The mathematical algorithm, which is put forward, has proven to
be effective through a practical numerical example.
