Abstract

Abstract

En 中文
• A key challenge in the online adaptation of direct data-driven methods is maintaining the persistence of excitation during online data updates. • Online system trajectories appropriate for direct data-driven prediction are linearized and stored for future use. • Based on the current system trajectory and the future reference trajectory, a suitable stored trajectory is selected for Hankel matrix construction. • The incorrect choice of trajectory in the application to nonlinear system control can vastly deteriorate the control quality. • The proposed controller ensures generality, stability, safety, and adaptability in a model-free direct data-driven manner.
