摘要: This paper deals with the simultaneous estimation of states and unknown inputs for a class Lipschitz nonlinear systems using only measured outputs. The system is assumed to have bounded uncertainties that appear on both state output matrices. observer design problem formulated as set linear constraints which can be easily solved matrix inequalities (LMI) technique. An application based manipulator arm actuated by direct current (DC) motor presented evaluate performance proposed observer. applied estimate faults.
