In this letter, a novel scheme is proposed to identify
in finite time the value of an unknown output parameter
for a class of nonlinear dynamical systems. Inspired by the
Super-Twisting Sliding Mode Algorithm (STA), the identification
problem is solved in an innovative way, consisting of two steps. An
STA observer is firstly designed to track in finite time the system
output. Exploiting the observer behaviour during the sliding motion, a second scheme, still inspired by the STA, is used to estimate
the unknown value of the output parameter, thus solving the
identification problem in finite time. The numerical simulations
based on district heating systems validate the effectiveness of the
proposed identification method.
