Following the work presented by the author in a previous paper, a model reference adaptive controller, which requires minimal knowledge of the system structures, is synthesized to control or synchronize chaotic systems. This is achieved by exploiting the boundedness of chaotic evolutions. Moreover, when the linear term of the error equation is characterized by a Hurwitz matrix, the control law is reduced to a pure discontinuous action, whose amplitude is adaptively estimated. The method is applied to the control of a Lorenz system and the synchronization of two dentical Chua circuits
