The uncertain version of almost disturbance decoupling problem with stability is defined and investigated for a class of nonlinear cascaded like systems with nonlinear parameter uncertainty. The synthesis provides a practical step by step procedure such that the influence from the disturbance to the controlled output can be arbitrarily small subject to nonlinear uncertainties, and internal system is asymptotically stable.
