"Intelligent Control and Optimization Techniques for Next-Generation Complex Dynamic Interconnected Systems"
Complex dynamic interconnected systems arise in many emerging applications in areas like surveillance, patrolling, smart grid, supply chain networks, multi-robot systems, biochemical reactions, interacting populations, and epidemics. Therefore, developing intelligent control and optimization techniques targeting such interconnected systems is of prime importance to advance the state of the art across many application domains.
However, several persistent challenges in this endeavor include handling concerns related to complexity, scalability, uncertainty, resiliency, security, and optimality. To address these challenges, it is paramount that we: (1) Identify and exploit unique structural properties behind each interested class of problems, (2) Develop and use rigorous theoretical concepts, and (3) Specialize and deploy cutting-edge techniques in control, optimization, artificial intelligence, and interconnected systems.
To showcase this approach, in this talk, I will discuss a selected set of control and optimization techniques developed for several interesting interconnected systems applications. They include: (1) Off-line and on-line control techniques developed for a generic class of multi-agent persistent monitoring problems with applications in surveillance, patrolling, distributed sensing, etc., and (2) Decentralized and compositional analysis, distributed controller synthesis and interconnection topology synthesis techniques developed for generic linear and non-linear networked systems with applications in smart grid, supply chains, multi-robotic systems, etc. I will conclude this talk by outlining several future research plans toward addressing fundamental challenges and exploring emerging applications of complex dynamic interconnected systems.
