摘 要：To conclude this monograph, we want to recall the general philosophy behind the approach developed from chapter to chapter as well as the difficulty we can encounter when designing a structured controller and thus the development that needs to be done. As a matter of fact there are three major concepts that have to be considered: the concept of system, and the concept of control intended to transform the original one into another with a more satisfactory behavior. This transformation is made through the use of a design procedure, which is the third concept we want to talk about.
