title = "Nonlinear Gain Extended State Observer Based Nonsmooth Funnel Control for Nonlinear Systems with Unknown Dynamics",
abstract = "For the second order nonlinear systems with unknown disturbances, a nonsmooth funnel control (NSFC) method with a novel extended state observer (ESO) is designed to constrain the tracking error. The unknown total disturbance is extended to a new state, and then a nonlinear gain ESO (NLG-ESO) is developed to estimate it. The 'peaking value problem' in the typical linear ESO (LESO) is addressed by the designed nonlinear gain, and the large observer gains in initial period is avoided. In addition, a funnel variable with the nonsmooth function is designed, and the NSFC can constrain the tracking error stay in a funnel zone with better tracking performance. Simulation results illustrate that the designed NSFC with NLG-ESO can achieve the control objectives.",
