Abstract: Since the topic of sliding mode control was introduced to the international control community following early pioneering work in the former Soviet Union in the 1960’s, the methodology has received a great deal of attention across a broad range of application domains. Fundamental to the approach is its total invariance to an important class of parameter variations and uncertainty. A further advantage is that the dynamic behaviour of the system may be directly tailored by the choice of a so-called switching function - essentially this switching function can be thought of as a measure of the desired performance. This presentation will begin with a review of the basic properties and terminology of such discontinuous controllers. By appealing to highly conserved and robust controllers from biology, the case for discontinuous control as an underpinning element for robustness in both the control and observation of large scale and complex systems will be made. Recent work with the automotive sector will then be considered where the disruptive effect of the introduction of electric vehicles has stimulated industry to completely revisit established designs and supply chains. Work will be described which has used sliding mode techniques to develop Anti-Lock Braking Systems (ABSs) for next generation electric vehicles. The performance of an intelligent hybrid distribution scheme, which accommodates the constraints of a regenerative braking system to achieve high energy recuperation across a range of braking modes will finally be reviewed.

Abstract: Despite the clear mandate towards the goal of carbon neutrality, the current pace of progress for the transition to renewable energy and the decarbonization of chemicals production is rather slow. The key challenge facing countries and industries is identifying low-carbon solutions that are economically feasible yet impactful in reducing greenhouse gas (GHG) emissions. Process systems engineering (PSE) is a field of research that applies methodological guidelines and systematic tools for process synthesis, design, operation, and evaluation. In this regard, PSE plays a critical role as an intermediary, bridging bench-scale R&D to higher-level policy and deployment decisions. In this talk, we examine the various paths to achieving carbon-neutrality including recycling, carbon capture and conversion, (CCU) and bioconversion, and important factors for them to succeed. We discuss the role of PSE tools, e.g., modeling, optimization, and life-cycle analysis, to assess their feasibilities and to build the most realistic path forward by combining them. Computer-aided tools for analysis and synthesis can be extremely helpful and the software called ArKaTAC3 being developed for this purpose will be introduced.

Plenary Speaker - Prof. Guy Dumont

Dr. Guy Dumont is a Professor of Electrical and Computer Engineering at UBC where he is an Associate Member of the Department of Anesthesia, Pharmacology and Therapeutics as well as an Associate member of the School of Biomedical Engineering.

From Process Control to Biomedical Engineering: The Broad Reach of Control Engineering

Abstract: Karl Aström once famously called automatic control the hidden technology in recognition of the fact that despite its pervasiveness, it is rarely mentioned. Control is indeed a critical component of numerous processes and technologies used in industry and in our everyday life. I want to illustrate the broad reach of control engineering through applications I performed over the last forty years. These include adaptive control of rotary kilns for the production of TiO2 pigments, robust cross-directional control of paper machines, adaptive control of continuous digesters, dual adaptive control of wood-chip refiners and paper coating, as well as a general-purpose adaptive controller based on Laguerre functions, that has been applied to the control of processes for the production of lime, glass, oil and gas, food and beverage. For the last two decades, working in close collaboration with clinicians I have focused on biomedical applications especially in critical care and automated intravenous anesthesia. For the last two years, COVID-19 has presented a challenge to the public health authorities. Fortunately, representing control of COVID-19 explicitly in a feedback framework, allows the rigorous design of transparent and effective public health policies, replacing ad-hoc policies. This requires control experts to work closely with epidemiologists and public health experts. Through this talk I want to illustrate the breadth of control applications and the sense of excitement a career in control can bring particularly when working in a multidisciplinary environment. I have been at it for some 45 years and still feel as passionate about my work as when I started, and I hope to convey this passion to our younger colleagues. We bring a unique perspective and have much to contribute to society at large. It is time to come out of hiding!
