Abstract
This study extends an MLF-based finite-time boundedness observer technique for nonlinear switched systems with Lipschitz structures subject to external disturbances for the first time. This plan makes sure that the system states to stay within a set bound when external disruptions of finite duration are taken into account. Additionally, the ‘jump high’ condition is used to loosen up the observer’s limitations. The “jump high” condition, on the other hand, places a dwell-time restriction on the switching signal. In order to lower the dwell-time limitation in comparison with other structures, the observer and switching signal are designed together with the PDT structure. In linear matrix inequalities, finite-time boundedness constraints are expressed as a feasibility problem that may be resolved using standard software. These restrictions modify the rate of energy changes in switching moments and estimation error dynamics so that the system states stay within the specified bound. Finally, a numerical simulation of an example is used to evaluate the effectiveness of the suggested system. The outcomes demonstrate that the suggested plan is effective.
