CURRENT/RECENT RESEARCH PROJECTS:

  • A Distributed Optimization-based Approach to Flexible Plantwide Control using Differential Dissipativity (ARC Discovery Project: DP180101717, 2018-2020, $383K)
    In today's demand-dynamic economy, the Australian process industry needs to shift from traditional mass production to smart manufacturing for more agile, cost-effective and flexible process operation responding to the market. While governments and industries worldwide have heavy invested in this new industry paradigm, developments are largely limited to its information technology aspect. This project will investigate the process control methodologies crucial to smart manufacturing. Based on contraction and dissipativity theories, this project aims to develop a distributed optimization-based nonlinear control approach for plantwide flexible manufacturing, which can achieve time-varying operational targets including production rates and product specifications to meet dynamic market demands. This includes a contraction-based nonlinear distributed control framework that ensures plantwide stability at any feasible setpoints or references and a distributed economic model predictive control approach that coordinates autonomous controllers to achieve plantwide economic objectives in a self-organizing manner. The outcomes of this project are expected to form a process control framework for next-generation smart plants.

  • Power Modulation of Aluminium Smelting Cells for Power Demand–Supply Balancing (ARC Industry Research Hub/Emirate Global Aluminium, 2020-2023, $1000K)
    The aluminium smelting process is very energy intensive, with Australia’s smelting industry consuming 29.5 TWh of electricity in 2007, representing 13% of total electricity generated in Australia. Existing aluminium smelting operations typically operate at constant current levels to reduce the variability of the smelting process and simplify process operation. However, this approach results in little flexibility in power modulation of smelting cells. New smelting process operation strategies, and cell monitoring and control approaches will be developed to allow flexible power modulation. This will enable the production rate of aluminium to be reduced or increased to match the supply of power and/or electricity prices. Such virtual storage can provide significant benefits to the stability and efficiency of the electricity network while reducing operating costs for aluminium producers. There are major challenges in power modulation of aluminium smelting cells. Variable amperage may lead to significant problems in heat balance of the cells and current efficiency, and abnormal conditions may occur if the smelting cells are not tightly controlled. Research will focus on (1) studying the feasible operation ranges that minimise irreversible damage to smelting cells based on coupled thermal and mass balance of the smelting cells; (2) cell monitoring approaches that can detect and thereby avoid any abnormal operation conditions caused by power modulation, including using individual anode current measurements, and (3) advanced process control approaches for tightly controlling operation of smelting cells with varying current, based on multivariable nonlinear control theory.

  • Advanced Distributed Cell Control for Aluminium Smelting Cells (Industrial Project sponsored by Emirate Global Aluminium, 2018-2020, $867K) 
    This project aims to develop a novel alumina feeder design and an advanced real-time cell control strategy  to achieve more uniform and smooth alumina concentration spatially and temporally, more uniform anode current distribution, and better distributed heat management, resulting in a more balanced and stable cell with reduced background perfluorocarbon emission and sludge formation.
    Supported by Emirate Global Aluminium, in collaboration with Prof. Barry J. Welch.
     
  • Advanced Anode Current Monitoring System for Aluminium Reduction Cells (Industrial Project sponsored by , 2019, $209K)
    This project aims to develop a prototype of the smart sensing system for monitoring aluminium reduction cells, which requires low maintenance. Soft-sensor techniques based on a multi-level extended Kalman filter is developed to estimate the important process variables in real time.
    Supported by Emirate Global Aluminium, in collaboration with Prof. Barry J. Welch.

  • An Integrated Approach to Distributed Fault Diagnosis and Fault-tolerant Control for Plantwide Processes (ARC Discovery Project: DP160101810, 2016-2018, $285K)
    Modern industrial processes are very complex, with distributed process units via a network of material and energy streams. Their operations increasingly depend on automatic control systems, which can make the plants susceptible to faults such as sensor/actuator failures. Occurrence of faults is increased by the common practice to operate processes close to their design constraints for economic considerations. This project will develop a new approach to detect and reduce the impact of these faults, which can cause significant economic, environment and safety problems. Based on the concept of dissipative systems, this project aims to develop a novel integrated approach to distributed fault diagnosis and fault-tolerant control for plantwide processes. The key dynamic features of normal and abnormal processes are captured by their dissipativity properties, which are used to develop an efficient online fault diagnosis approach based on process input and output trajectories, without the use of state estimators or residual generators. Using the dissipativity framework, a distributed fault diagnosis approach will be developed to identify the locations and faults in a process network. A distributed fault tolerant control approach will be developed to ensure plantwide stability and performance. 
    Supported by the Australian Research Council.
     
  • Control of Distributed Energy Storage System using Vanadium Batteries (ARC Discovery Project DP150103100, 2015-2017, $341K)
    The ever increasing integration of distributed renewable energy generation sources with the electricity grid reduces our reliance on fossil fuels and carbon emissions but also presents risks to the grid’s stable and reliable operation due to intermittent nature of such sources. This project will develop some key technologies of battery energy storage and control to address the above issues and help defer the investment for the augmentation of the transmission and distribution networks. This project aims to develop a new control approach to distributed energy storage at stack, system and microgrid levels, utilising one of the most promising flow battery technologies - Vanadium Redox batteries. This is the first attempt of a storage centric approach that includes (1) an integrated approach to design and control of Vanadium flow batteries with novel advanced power electronics technologies to achieve optimal charging/discharging conditions and (2) a scalable distributed energy storage and power management approach incorporating energy pricing for storage dispatch that allows distributed autonomous controllers to achieve optimal local techno-economic performance and microgrid-wide efficiency and reliability.
    Supported by the Australian Research Council. In collaboration with Prof. Maria Skyllas-Kazacos.
