Abstract

The use of orthogonal collocation methods in the solution of various optimal control problems relating to Formula One racing will be discussed. These methods can be used to optimise driver controls such as the steering, brakes and throttle, and optimise vehicle setup parameters such as the aerodynamic down force distributions, the suspension system and the engine maps. Of particular interest is the optimal usage of on-board energy recovery systems. The lecture will focus on the control of the hybrid kinetic-thermal energy recovery systems known as (ERS-K) and (ERS-H) that have been introduced into Formula One racing for the 2014 season. It is demonstrated that these systems, when properly controlled, can produce contemporary lap time using approximately two thirds of the fuel required by legacy (2013 and earlier) vehicles.

Babatunde Ogunnaike (University of Delaware, US)

Abstract
The mammalian organism maintains stable, efficient and “near-optimal” performance and homeostasis in the face of external and internal perturbations via distinct biological systems ranging from the large-scale physiological (nervous, endocrine, immune, circulatory, respiratory, etc.), to the cellular (growth and proliferation regulation, DNA damage repair, etc.), and the sub-cellular (gene expression, protein synthesis, metabolite regulation, etc). “Biological Control Systems,” a sub-topic of Control Theory, arises from a control engineering perspective of the function, organization, and coordination of these multi-scale biological systems and the control mechanisms that enable them to carry out their functions effectively.

In this presentation, we will provide an overview of how physiological life is made possible by control, and demonstrate the usefulness of a control engineering perspective of pathologies for diagnosis, design, and implementation of effective treatments. The concepts and principles will be illustrated using three specific examples with significant research and clinical implications: Ca++ Regulation; TGF-β and prostate cancer; and Platelet Deficiency Control.

The Ogunnaike group is interested in understanding the dynamic behavior of complex systems through mathematical modeling and analysis, and then exploiting this understanding for postulating novel designs and improved operation. Specific systems of interest range from polymer reactors, particulate processes and extruders, to biological processes at the cellular and physiological levels. Specific research topics include modeling and control of industrial processes (polymer reactors, extruders, distillation columns); the application of process analytical technology for control of pharmaceutical processes; modeling and control of hybrid renewable energy systems; biological control systems; and systems biology with application to neuronal responses and cancer.

Bozenna Pasik-Duncan, (University of Kansas, US)

Abstract
Stochastic adaptive control denotes the control of a partially known stochastic system. While stochastic models are developed from physical systems, typically some parameters of the model are unknown but the systems have to be controlled. Thus there is a problem of stochastic adaptive control. A solution to it consists of parameter estimation and control. The noise processes for the models include some that have been empirically identified in cognition, that is, fractional Brownian motions. Stochastic control and stochastic adaptive control problems are described for systems with a noise modeled by fractional Brownian motions and other stochastic processes. Applications of stochastic adaptive control include telecommunication, biomedicine, and finance. One can also view education in the STEM subjects as a problem of adaptive control. The learning process is stochastic and there are some well-defined objectives. A major question is how to achieve success for such a problem. The methods from theoretical aspects of stochastic adaptive control have been also applied to the educational processes in STEM.

Guanrong Chen (City University of Hong Kong, Hong Kong)

Abstract
In this talk, we discuss the complete state controllability of networked higher-dimensional linear time-invariant dynamical systems interconnected by directed and weighted higher-dimensional channels. We show how the network topology, node-system dynamics, external pinning control inputs, and inner interactions affect the controllability of such a complex dynamical network. We present precise necessary and sufficient conditions for the network controllability in a general setting, as well as in some special configurations with more subtitle analysis.

Thokozani Majozi (University of the Witwatersrand, South Africa)

Abstract
The lecture provides background on optimization and its applications in process systems engineering. A particular emphasis is placed on time dependent processes, the so-called batch chemical processes. These operations remain elusive to traditional optimization techniques, due to their structural complexity. In essence, it has been proven that these operations are NP-Hard, thereby rendering a search for global optimality largely impractical for real-life problems. This has led to most researchers resorting to heuristic, stochastic and evolutionary optimization techniques.

In its ultimate analysis, the lecture dwells on two areas in which process systems engineering has been applied with great success. The first area involves synthesis, design and optimization of batch chemical facilities using a robust scheduling framework. The second area pertains to optimization of integrated water and membrane network systems. These systems are characterised by intensive energy requirements as they seek to minimize overall freshwater use and wastewater generation. Consequently, the idea is to simultaneously optimize these inherently complex systems in terms of both energy and water requirements.

Tianyou Chai (Northeastern University, China)

China has abundance of mineral resources such as magnesite, hematite and bauxite, which constitute a key component of its economy. The relatively low grade, and the widely varying and complex compositions of the raw extracts, however, pose difficult processing challenges including specialized equipment with excessive energy demands. The energy intensive furnaces together with widely uncertain features of the extracts form hybrid complexities of the system, where the existing modeling, optimization and control methods have met only limited success. Currently, the mineral processing plants generally employ manual control and are known to impose greater demands on the energy, while yielding unreasonable waste and poor operational efficiency. The recently developed Cyber-Physical System (CPS) provides a new key for us to address these challenges. The idea is to make the control system of energy intensive equipment into a CPS, which will lead to a smart optimization control system.

This talk presents the syntheses and implementation of a smart optimization control system for energy-intensive equipment under the framework of CPS. The proposed smart optimization control system consists of three main functions: (i) process control; (ii) setpoint optimization control; and (iii) fault diagnosis and self-recovery control. The key in realizing the above functions is the algorithm structure which is able to integrate control, optimization, fault diagnosis and self-recovery control together seamlessly.  This talk introduces the algorithm structure for integrated implementation of setpoint optimization control, process control and fault diagnosis and self-recovery control.

Hardware and software platform of smart optimization control system for energy-intensive equipment is then briefly introduced, which adopts embedded control system, wireless network and industrial cloud. It not only realizes the functions of computer control system using DCS (PLS), optimization computer and fault diagnosis computer, but also achieves the functions of mobile and remote monitoring for industrial process.

Then, using fused magnesium furnace as an example, a hybrid simulation system for smart optimization control system for energy-intensive equipment developed by our team is introduced. The results of simulation experiments show the effectiveness of the proposed method that integrates the process control, setpoint optimization control and fault diagnosis and self-recovery control in the framework of CPS.

The industrial application of the proposed smart optimization control system is also discussed. It has been successfully applied to the largest magnesia production enterprise in China, resulting in great returns. Finally, future research on the smart optimization control system is outlined.
