摘要：

The disturbance observer based stabilization of a generalized linear uncertain system is studied. All the states variables are assumed to be immeasurable and are not available in feedback to the designed controller and disturbance estimator. Firstly, for the purpose of state estimation Luenberger observer is investigated. In addition, to eradicate the influence of norm bounded disturbance a linear disturbance observer is designed in the second step. Finally, an algorithm based on state feedback controller is designed to regulate the states trajectories to the origin. To validate the effectiveness of proposed scheme a numerical example is provided.
