A novel dual adaptive controller for extremum control of stochastic and uncertain nonlinear Hammerstein systems is proposed. The design is based on the innovations dual control cost function originally developed for conventional adaptive control of l

Mathematical models explaining the dynamics of the mixer-settler unit are investigated. It is shown that the static model is inadequate in this context and a two-part dynamic model is proposed.

This paper proposes a dual adaptive control methodology for extremum control of stochastic Hammerstein systems that are subject to uncertainty and characterised by a nonlinear second-order polynomial function. The design is based on an explicit-type

In this work, the problem of designing feedback controllers for the rejection of narrow-band disturbances is considered. The design technique proposed herein is based upon the overparameterization of a nominal minimum-variance controller, which is de
