Layered Control of Partially Observed Stochastic Systems
Charis Stamouli, Anastasios Tsiamis, George J. Pappas
Layered control is essential for managing complexity in large-scale systems, employing progressively coarser models at higher layers. While significant advances have been made for…
On transferring safety certificates across dynamical systems
Nikolaos Bousias, Charalampia Stamouli, Anastasios Tsiamis +1
Control barrier functions (CBFs) provide a powerful tool for enforcing safety constraints in control systems, but their direct application to complex, high-dimensional dynamics is…
Policy Gradient Bounds in Multitask LQR
Charis Stamouli, Leonardo F. Toso, Anastasios Tsiamis +2
We analyze the performance of policy gradient in multitask linear quadratic regulation (LQR), where the system and cost parameters differ across tasks. The main goal of multitask L…
Layered Multirate Control of Constrained Linear Systems
Charis Stamouli, Anastasios Tsiamis, Manfred Morari +1
Layered control architectures have been a standard paradigm for efficiently managing complex constrained systems. A typical architecture consists of: i) a higher layer, where a low…
