Dependable Control and Decision group

DECODE – Dependable Control and Decision group

The DECODE (Dependable Control and Decision) group focuses on complex control systems, where coupling between subsystems, local sources of uncertainty, and structural changes can undermine reliability and generate dangerous behaviors. By leveraging tools from control theory, optimization, and machine learning, we contribute to the development of next-generation systems that are dependable, more autonomous and self adapt to changes in the internal dynamics and the surrounding environment.

The DECODE group is part of the Automatic Control Laboratory and the NCCR automation.

Performance and safety guarantees from NOISY data! *New Preprint*

— Solely using noisy historical data, we synthesize a robustly safe output-feedback policy, for which the suboptimality and safety gaps are explicitly and tightly upperbounded in terms of the level of corrupting noise. This is achieved by developing a new tractable optimal control method, the Behavioral Input-Output Parametrization (BIOP), which first exploits behavioral theory to identify a precise impulse response, and then sets up a quasi-convex optimal control procedure with guaranteed high performance.  Check out our preprint!

State estimation using data: we have a new preprint on arXiv!

— Our new technical report "Data-driven Unknown-input Observers and State Estimation" leverages the recently developed behavioral system theory to propose a completely data-driven framework for unknown-input observers and regular state estimation.

Our technical report on data-driven control is out

— The paper, entitled "A Data-Driven Convex Programming Approach to Worst-Case Robust Tracking Controller Design", uses behavioral system theory to provide a convex-programming-based framework for solving worst-case optimal tracking problems in a data-driven fashion. It also guarantees that input/output constraints are always satisfied when the output data are noisy and inputs have disturbances.
