On the Robustness in Data-Driven Nonlinear Optimal Control: From Stability to Optimality

Yicheng Lin, Zhisheng Duan, Tianzhi Li, Bingxian Wu, Zhiyong Sun

In data-driven nonlinear control, optimal controllers designed from learned models are inevitably subject to model mismatch when deployed on actual systems, potentially compromising both closed-loop stability and optimality. This paper investigates how the model mismatch propagat…
