Abstract
In this paper, a global finite-time observer is designed for a class of nonlinear systems with non-Lipschitz conditions. Compared with the previous results, the observer designed in this paper is proposed with a new gain update law. By two examples, we show that the proposed observer can reduce the time of the observation error convergence.
