Meta-Learning for Rapid Adaptation in Reference Tracking of Uncertain Nonlinear Systems
Researchers have developed a novel meta-learning framework for designing optimal controllers for uncertain nonlinear systems, particularly when target system data is scarce. This approach leverages offline data from similar source systems to accelerate training and improve control performance in an online adaptation phase. The framework is formulated as a bi-level optimization problem and can integrate various learning algorithms, including neural state-space models and deep Q-networks, demonstrating enhanced performance over baseline methods in simulations and hardware experiments.
