The problem of designing an adaptive delay-state observer for a class of nonlinear systems is investigated by using output differential and sliding mode methods. First, the differential output of the system and the output of the higher-order differential are expressed as the difference quotient of the delayed measurement, Based on which a delay state observer is constructed and the influence of the estimation error can be eliminated by the sliding mode term.An adaptive delay state observer design is given under the condition that the system satisfies the linear parameterization.Finally, Research shows the effectiveness of design methods.
