The technical program will comprise several types of presentations in regular and invited sessions, tutorial sessions, and special sessions along with workshops and exhibits. An important goal of the conference is to bring forward the role of. PID control in the new Industry 4.0 context and listen to the challenges from both industry and academia.

Title: PID control of dead-time process: robustness, dead-time compensation and constraints handing

Abstract: PID controllers are widely used to control dead-time processes. As dead time is a dynamic behavior normally found in many industrial plants, to find appropriate tuning rules and operational conditions of PIDs for such processes is very important. This work tackles, using a unified approach, valid for stable, integrating, and unstable dead-time processes, a methodology to tune and configure PID control loops. The main ideas of the proposed approach are to use dead-time compensation concepts to obtain the PID tuning and to consider adequate anti-windup strategies to overcome the effects of saturations of the increments and absolute values of the control action. Robustness aspects, stability analysis and optimal or sub-optimal conditions are analyzed to understand the limitations of the solutions. Model predictive control algorithms are used to show how almost optimal solutions can be obtained with the proposed anti-windup PID controllers under control action constraints. Moreover, the advantages or disadvantages of using the proposed PID strategy instead of more sophisticated dead-time compensation algorithms with anti-windup are discussed. Several case studies are presented to illustrate the main ideas and to compare the obtained results with other existing methods. Experimental results are also included to discuss implementation issues.

Title: New PID designs for sampling control and batch process optimization

Abstract: Owing to overwhelming development of digital control technologies in modern industrial engineering and manufacturing, advanced PID designs have been widely appealed for implementation in sampled control systems. In this lecture, a few up-to-date PID designs for practical applications subject to operating constraints and measurement noise will be presented, based on our research results explored in the past years. For industrial batch processes and periodic systems, by using historical cycle data, iterative learning type PID control system designs will be introduced to realize perfect tracking of the set-point profile against unknown process uncertainties and repetitive load disturbances, along with robust tuning methods to accommodate for time-varying uncertainties or disturbances from cycle to cycle. Finally, some perspective and challenges on PID design are pointed out, hoping to draw more attentions by scholars and engineers in the field of control engineering.

Title:Industrial loop tuning in the digital age

Abstract: The digital era of automation has unleashed potential for improvements in production, quality, and reduced cost to produce. However these advances have come with a cost. That cost is the nearly exponential expansion of digital equipment available to our technicians and engineers. No longer is the number of controllers limited to the physical constraints of a control room wall. Today a controller can be a pixel on a screen. What once may have been less than 50 controllers can now easily be well over 500 for an industrial process area. This expanse coupled with digital security, software revision control, user interface ergonomics, alarm management, software back ups, control scheme interactions, has actually reduced the amount of time a control engineer can spend simply tuning a loop. As a result we are seeing an industrial break down in the quality of PID loop performance in all industrial sectors. ABB is taking proactive measures to reduce the problem space so that engineers can no what to tune, when to tune, and how to tune so that optimal performance can be achieved. This discussion will focus on how we can expand our engineers circle of influence so they can manage this exciting digital era.



During the conference three sessions will be organized.

Industry 4.0 Challenges - Companies may present problems, study cases, trends




The PID 2018 conference is traditionally an opportunity for interaction between academia and industry. To better acknowledge the industry needs and academic solutions, and map them for better synergy, an open panel discussion session will be organized on the second day of the conference. This is accessible for all participants to attend and interact with the panel contributors. The panel for industry will take place on the 2nd day of the conference, May 10, 2018.

More information will follow shortly.

Control education - Are our students ready for Factory of the Future?




The PID 2018 conference is a great opportunity to present and discuss the latest advances in control education. Novel tools for computer aided design, low-cost and effective benchmarks and other educational aspects are the core elements of an open panel discussion during the third day of the conference.

Additionally, a parallel track on internet based control education will be featured on the 1st day of the conference, May 09, 2018. More information can be found (click here ) This will be open for all participants to attend and interact with the panel contributors.

More information will follow shortly.
