Local Sensitivity Analysis for Kernel-Regularized ARX Predictors in Data-Driven Predictive Control
Aihui Liu, Magnus Jansson
We study local sensitivity of structured ARX-based data-driven predictive control. Although predictor estimation is linear in the ARX parameters, the lifted multi-step predictor us…

The Innovation Null Space of the Kalman Predictor: A Stochastic Perspective for DeePC
Aihui Liu, Magnus Jansson
Willems' fundamental lemma uses a key decision variable to combine measured input-output data and describe trajectories of a linear time-invariant system. In this paper, we ask…

Closed-Loop Consistent, Causal Data-Driven Predictive Control via SSARX
Aihui Liu, Magnus Jansson
We propose a fundamental-lemma-free data-driven predictive control (DDPC) scheme for synthesizing model predictive control (MPC)-like policies directly from input-output data. Unli…
