The Proportional, Integral and Derivative –PID– controller is the most widely used controller in industrial applications. Since its first appearance in the late nineteen century, it had attracted researchers from all over the world because of its simplicity and the ability to provide an excellent control performance. The PID controller now represents more than ninety percent of the controllers used in the market. This book is a result of contributions and inspirations from many researchers worldwide in the field of control engineering. The book consists of two parts; the first is related to the implementation of PID control in various applications whilst the second part concentrates on the.
