An Actor Critic Method for Free Terminal Time Optimal Control
Evan Burton, Tenavi Nakamura-Zimmerer, Qi Gong +1
Optimal control problems with free terminal time present many challenges including nonsmooth and discontinuous control laws, irregular value functions, many local optima, and the c…
Neural Network Optimal Feedback Control with Guaranteed Local Stability
Tenavi Nakamura-Zimmerer, Qi Gong, Wei Kang
Recent research shows that supervised learning can be an effective tool for designing near-optimal feedback controllers for high-dimensional nonlinear dynamic systems. But the beha…
Machine Learning based Optimal Feedback Control for Microgrid Stabilization
Tianwei Xia, Kai Sun, Wei Kang
Microgrids have more operational flexibilities as well as uncertainties than conventional power grids, especially when renewable energy resources are utilized. An energy storage ba…
The Observability in Unobservable Systems
Wei Kang, Liang Xu, Hong Zhou
In this paper, we introduce the concept of observability of targeted state variables for systems that may not be fully observable. For their estimation, we introduce and exemplify…
Data-Driven Computational Methods for the Domain of Attraction and Zubov's Equation
Wei Kang, Kai Sun, Liang Xu
This paper deals with a special type of Lyapunov functions, namely the solution of Zubov's equation. Such a function can be used to characterize the domain of attraction for system…
Neural network optimal feedback control with enhanced closed loop stability
Tenavi Nakamura-Zimmerer, Qi Gong, Wei Kang
Recent research has shown that supervised learning can be an effective tool for designing optimal feedback controllers for high-dimensional nonlinear dynamic systems. But the behav…
