Abstract
Robust stochastic adaptive control in the presence of unmodeled dynamics and external disturbances is considered. It is assumed that multiplicative and additive system perturbations and external disturbances are complex, unstructured, and large at high frequencies. Global stability is established without requiring the minimum phase assumption and persistency exciting conditions. The self-stabilization mechanism of the proposed adaptive control algorithm is characterized analytically
