Creating some links between control feedback and biology modeling communities based on similarities in modeling observing and perceiving alive structures and analyzing interconnections between biological structures and subsystems was the main objective of this volume. In this context biology systems need appropriate analysis tools due to their structure and hierarchy complexity and environment interference and we believe that these aspects may generate interesting research topics in control area. Indeed several works raising the potential impact of control developments to bring some beginning of answers in the context of biological systems have been published in the recent years. The idea of this book was conceived in the context mentioned above with the objective to help in claiming many of the problems for control researchers starting discussions and opening interactive debates between the control and biology communities and finally to alert graduate students to the many interesting ideas at the frontier between control feedback theory and biology. .
