Abstract:

In recent years, with the vigorous development of swarm intelligence in agriculture, industry, economy and other fields, the cooperative decision-making and control problem of large-scale intelligent, autonomous, and multi-functional swarm unmanned systems has received extensive attention. Among them, heterogeneous networked systems are more conducive to the implementation of cluster collaborative tasks due to their stronger task adaptability, higher system robustness, and higher resource utilization. This report mainly focuses on two kinds of decision-making and control problems, cooperative optimization and non-cooperative game control in heterogeneous networked systems, and constructs a decision-making and control integrated architecture. Based on output regulation theory, event-triggered control techniques and dynamic gain regulation methods, the decision-making and control scheme of cooperative optimization and non-cooperative game for heterogeneous networked systems is given. It achieves a fully closed loop, high robustness, and strong real-time control pattern. Finally, we discuss the prospects of integrating cooperative optimization and non-cooperative game problems with artificial intelligence techniques such as reinforcement learning and data-driven methods.

Our Mission

The Centre for Complexity and Complex Networks aims to conduct emerging and cutting-edge research in the multidisciplinary area of complex systems and networks, including fundamental theory in dynamical networked systems and cyber physical systems, and applications in

  • epidemic progression modelling
  • energy systems and power grids
  • information and communication systems
  • transportation networks
  • resilience of critical infrastructures
  • cryptocurreny and blockchains
  • business and finance

Through the significant and groundbreaking contributions of its members to the fundamental theory of nonlinear science and applications over the past 20 more years, the centre has established itself as one of the leading research centres in the world focusing on nonlinear science, complexity and complex systems.

Our centre promotes inter-institutional and interdisciplinary collaborations, and supports the industrial and business development of Hong Kong and the mainland via technology transfer and joint research projects.
