Output Feedback Stabilization by Reduced Order Finite Time Observers using a Trajectory Based Approach

Abstract : We use finite time reduced order continuous-discrete observers to solve an output feedback stabilization problem for a broad class of nonlinear systems whose output contains uncertainty. Unlike earlier works, our feedback control is discontinuous, but it does not contain any distributed terms. We use a trajectory based approach based on a contractivity condition. We illustrate our new control design using a tracking problem for nonholonomic systems in chained form.
