Finite Time Output Parameter Estimation for a Class of Nonlinear Systems

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