Adaptive Neural Control for Output Feedback Nonlinear Systems Using a Barrier Lyapunov Function
A barrier Lyapunov function (BLF) is introduced to address two open and challenging problems in the neuro-control area: for any initial compact set, how to determine a priori the compact superset on which NN approximation is valid; and how to ensure that the arguments of the unknown functions remain within the specified compact supersets.
Adaptive neural control of uncertain MIMO nonlinear systems
Adapt neural control schemes are proposed for two classes of uncertain multi-input/multi-output (MIMO) nonlinear systems in block-triangular forms that avoid the controller singularity problem completely without using projection algorithms.

A smooth and singularity-free adaptive controller is designed for a first-order plant and an extension is made to high-order nonlinear systems using neural network approximation and adaptive backstepping techniques, guaranteeing the uniform ultimate boundedness of the closed-loop adaptive systems.
