Welcome to ACCL!
Our group focuses on research at the convergence of control theory and artificial intelligence and their applications in robotics, energy storage, and fault diagnostics and prognostics. We aim to develop resource-aware control, computationally efficient real-time learning, and smart battery management systems for health-conscious decision-making.
Control of Cyber-Physical Systems: With the recent development of spatially distributed systems, the spatiotemporal behavior, significant communication requirements, inevitable network constraints, and exposure to vulnerabilities (privacy and security) added another layer of complexity to developing control algorithms. Autonomous systems connected over communication networks must learn uncertain dynamics and environments, detect impending failure or attacks, swiftly isolate the compromised component, modify control, and resume stable operation.
Artificial Intelligence (AI) for Control: AI is a broad area of research. Real-time learning for control is notoriously challenging. The resource constraints of the edge devices, lack of dependable, high-confidence, or provable behaviors, safety, security, and verification in human-in- or human-on-the-loop systems make it more difficult to implement.

Application Areas
Lithium-ion batteries are the workhorse of electric vehicles. A battery management system is required for their safe operation, power, energy, and thermal management. Some of the primary challenges in battery management systems research are accurate state of health estimation, real-time learning of battery models, internal faults detection, and vulnerability to thermal runaway.
Electric Machinery Health Management is critical to avoid unprecedented downtime and cost. Our goal is to embed machines with advanced and intelligent fault diagnostics and prognostics algorithms to self-detect faults and predict remaining life.
