Convergence and well-posedness properties of uniformly locally contractive mappings

Topological Methods in Nonlinear Analysis, 2023
In a 1961 paper by E. Rakotch it was shown that a uniformly locally contractive mapping has a fixed point. In the present paper we show that for such a mapping, the fixed point problem is well posed and that inexact iterates of such a mapping converge

Dynamic learning from adaptive neural control for full-state constrained strict-feedback nonlinear systems

Neural Networks, 2023
This study focuses on the learning and control issues of strict-feedback systems with full-state constraints. To achieve learning capability under constraints, transformation mapping is utilized to convert the original system with full-state constraints ...
