Output Feedback Stabilization for a Class of Lipschitz Nonlinear Systems

SUMMARY In this letter, we provide a solution to the stabilization problem of a class of Lipschitz nonlinear systems by output feedback. Via the newly proposed nonlinearity characterization function (NCF) concept, we propose an effective method in designing an output feedback controller. Under the suggested sufficient condition which is derived by using the NCF, the proposed control scheme achi...

Robust Stabilization Approach and H∞ Performance via Static Output Feedback for a Class of Nonlinear Systems

This paper deals with the stability and stabilization problems for a class of discrete-time nonlinear systems. The systems are composed of a linear constant part perturbated by an additive nonlinear function which satisfies a quadratic constraint. A new approach to design a static output feedback controller is proposed. A sufficient condition, formulated as an LMI optimization convex problem, i...

Robust event-triggered output feedback controllers for nonlinear systems

We address the robust stabilization of nonlinear systems subject to exogenous inputs using event-triggered output feedback laws. The plant dynamics is affected by external disturbances, while the output measurement and the control input are corrupted by noises. The communication between the plant and the controller is ensured by a digital channel. The feedback law is constructed in continuous-t...

Robust Output Feedback Controller Scheme for a Class of Uncertain Nonlinear Systems

In this study, we present a new continuous output feedback type controller mechanism for the tracking problem of a class of uncertain nonlinear systems. The proposed strategy requires the uncertainties of the dynamical system to be first order differentiable and achieves semi-global asymptotic tracking when only the system outputs are measurable. The Controller design is based on a Lyapunov-typ...
