Model Free Adaptive Control: Theory and Applications

The book is horrible! Bad English, wrong and inconsistent notations, and difficult to follow.As an example, Eq. (2.3) is as follows:y(k)=f^T(k-1)q_0But immediately you see that authors say \phi(k-1) for f(k-1) and \theta_0 for q_0.Never buy this book. It will be a waste of money.
