An adaptive observer design approach is proposed for the class of nonlinear locally Lipschitz systems. The case of disturbances affecting the state equations is considered. The proposed solution is applicable to the systems with bounded solutions and hyperminimum phase linear part. It is based on the logic‐based control approach. Efficiency of the proposed observer design is demonstrated through computer simulations for Duffing and satellite system. Copyright © 2010 John Wiley & Sons, Ltd.
