Continuous Adaptive Robust Control for Nonlinear Uncertain Systems

We consider nonlinear uncertain systems such that a 
priori information of the uncertainties is not available. For such 
systems, we assume that the upper bound of the uncertainties is 
represented as a Fredholm integral equation of the first kind and we 
propose an adaptation law that is capable of estimating the upper 
bound and design a continuous robust control which renders nonlinear 
uncertain systems ultimately bounded.
