This paper presents an adaptive observer design for nonlinear systems that have parametric uncertainties in the unmeasured state dynamics. Without persistency of excitation (PE) the convergence of the state estimation error to zero is proved. Under PE conditions, uniform global asymptotic stability of the origin of the state and parameter error is shown. Furthermore, if the regressor is sufficiently...
A sliding mode controller with the adaptive parameters is proposed for a class of uncertain nonlinear systems such that the sliding mode parameter lambda , the approximate sign function parameter mu , the tendency rate k0 and the gain parameter eta be scheduled by the system states. Meanwhile, the obtained systems have the desired stable sliding mode motions with the appropriate parameters lambda...
A robust adaptive neural network control scheme is proposed for a class of strict-feedback nonlinear systems with unknown control directions and unmodeled dynamics. The proposed design method expands the class of nonlinear systems for which robust adaptive control approaches have been studied. A priori knowledge of the signs of the control directions is not required. It is proved that under the proposed...
