At the beginning of the new millennium the PID controller continues to be a key component of industrial control. During this century many different structures of control have been proposed to overcome the limitation of the PID controllers. Because of their simplicity and usefulness, they give a very useful solution to an important part of the industrial processes.
The present-day structure of PID controllers is quite different from the original analog PID controllers. Now the implementation of the PID is based on digital design, these digital PIDs include many algorithms such as anti-wind-up, auto-tuning, adaptive, and fuzzy fine tuning to improve their performances, but the basic actions remain the same.
During the last two decades, the general reluctance of researchers to use PID controllers has begun to disappear. Many of the new capabilities of digital PID controllers have been introduced by the research community. The industrial control users apply these innovations easily, even enthusiastically. PID control has become one of the most important ways for the scientific specialist in control and the users of industrial control to work together.
This workshop was organized so that the scientific world and the industrial control world could meet and discuss the present and future use of PID controllers - the successes and failures of their use and how to determine the limits of performances. This workshop was also useful for learning about control history, since the origin and evolution of PID control can provide us with keys for new development and designs.
For researchers working towards industrial applications of PID controllers and technologists interested in applying PID controllers in novel situations.
