Advances in Control and Stability of Nonlinear Systems

The field of control and stability of nonlinear systems is moving towards the development of innovative algorithms and frameworks that can handle unknown dynamics, uncertainties, and complex disturbances. Researchers are exploring new approaches, such as data-driven methods, neural networks, and Lyapunov functions, to improve the stability and safety of autonomous systems. Notably, the use of machine learning techniques is becoming increasingly popular for learning stability certificates, identifying disturbances, and controlling nonlinear systems.

Some noteworthy papers in this area include: Learning Stability Certificate for Robotics in Real-World Environments, which introduces a novel framework for learning Lyapunov functions from trajectory data. Delay Independent Safe Control with Neural Networks, which presents a risk-aware safety certification method for autonomous control systems using neural networks. A Dimension-Decomposed Learning Framework for Online Disturbance Identification in Quadrotor SE(3) Control, which proposes a new perspective on learning-based methods for identifying disturbances in high-dimensional systems.
