While there are thousands of books written about feedback control, it is surprising that this is the very first book about feedforward control. Feedforward control is a very powerful technique to compensate for measurable load disturbances in regulation control problems, and the use of feedforward control to assist the traditional feedback controllers is rapidly increasing in industry. The main goal of this book is to describe the power of feedforward control and to present different tuning rules for these controllers. To achieve this goal, theoretical and practical contributions are presented throughout the book to make the technique understandable and easy to implement. The book contains many practical aspects, both in terms of tuning and implementation of the feedforward controller. Many simulation examples are also provided, as well as a presentation of industrial experiences obtained from feedforward control applied to temperature control in greenhouses. For these reasons, we believe that the book will be useful not only at various levels in the teaching systems, but also for engineers working in industry.
