RECENT RESEARCH ACTIVITIES:
§ A
Network Approach to Process Control Based on the Dissipativity and Network
Theory
This project aims to develop a new
framework of plantwide process control for increasingly complex process systems
in chemical industry. Conventional modular approaches to process modelling and
control lead to very complex designs and thus are no longer suitable for modern
and future chemical plants. The proposed approach models the plantwide process
as a network of process units that interact through information and material
flows. Based on the dissipativity of each process unit and process network
topology, scalable, reliable and high performance control approaches (including
decentralized and distributed control) will be developed.
§ Dynamic
Controllability Analysis for Plantwide Process Design and Control
Based on the concept of passive systems, this project aims to develop a new quantitative measure for dynamic controllability for design of plantwide process systems. Integration of process design and control has been widely recognized as an effective approach to improving process performance to meet increased economic, safety and environmental demands. Controllability evaluation plays an important role in this approach. The outcome of this research will be an easy to use controllability analysis method for nonlinear plantwide multi-unit systems, which can be used in early stages of process design to explore better opportunities for process improvements.
World-wide chemical plants represent many billions of dollars of investment. Improvements to the process designs in terms of controllability would have the potential to provide large economic benefits, as it implies improved productivity, reduced operating costs and product variability. This proposed research will be a step towards integration of process design and control, which has been widely recognized as the key to this improvement. The outcomes from this project may be readily implemented in process design practice, and therefore may have a direct impact to the Australian and world-wide process industries, helping to build a more efficient and environmental conscious Australian process industries. (Supported by the Australian Research Council. In collaboration with Prof. P.L. Lee, University of South Australia)
§ Advanced
Control of Membrane Processes
This work aims to develop a dynamic process model and advanced control schemes for pressure driven membrane systems. Current methodologies, while functional, are conservative, narrow and slow and do not take advantage of process improvements achievable with tight active control. The expected outcomes include a validated model, control strategies that maximize productivity and minimize fouling during normal operation as well as during start-up and shut-down. (Supported by Australian Research Council. In collaboration with Prof. D.E. Wiley)
§ Soft Sensor Development for Mineral Processes Aided by Discrete Element Models
This project develops a new soft sensor
approach for mineral processes using discrete element models, exemplified by a
milling process. Monitoring and control of milling conditions is of
considerable interest to industry as grinding is the most energy intensive
process in mineral processing. However, direct monitoring of comminution
processes is not feasible due to the hostile environment inside the mills. By
using the discrete element models of milling processes, key process variables
and operating conditions inside the mills are simulated. Using both
multivariate statistical methods and the Gaussian process modelling technique,
the simulation results are then used to train soft sensor models that can
identify online the collision energy and the operating regions in terms of
breakage, from surface vibration measured during the milling operation.

collaboration with Prof.
Aibing Yu)
§ Decentralised Failure Tolerant Control Based on the
Passivity Theorem
Based on the Passivity Theorem, this project will develop a new approach to fault-tolerant decentralised control for both linear and control-affine nonlinear processes in a unified framework. Decentralised control is the norm in process industries and as such this project will provide rigorous tools to improve the performance and reliability of such control systems. Analysis methods for decentralised unconditional stability are being investigated and design methods for fault-tolerant high performance controllers are being developed. Theoretical results will be evaluated by experimental case studies of control of a pilot distillation column and a mineral processing pilot plant. This research also provides novel performance analysis tools for decentralised control. (Supported by Australian Research Council. In collaboration with Prof. P.L. Lee, University of South Australia)
