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…
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…
QRnet: optimal regulator design with LQR-augmented neural networks
Tenavi Nakamura-Zimmerer, Qi Gong, Wei Kang
In this paper we propose a new computational method for designing optimal regulators for high-dimensional nonlinear systems. The proposed approach leverages physics-informed machin…
Adaptive Deep Learning for High-Dimensional Hamilton-Jacobi-Bellman Equations
Tenavi Nakamura-Zimmerer, Qi Gong, Wei Kang
Computing optimal feedback controls for nonlinear systems generally requires solving Hamilton-Jacobi-Bellman (HJB) equations, which are notoriously difficult when the state dimensi…
Sparsity-Based Kalman Filters for Data Assimilation
Wei Kang, Liang Xu
Several variations of the Kalman filter algorithm, such as the extended Kalman filter (EKF) and the unscented Kalman filter (UKF), are widely used in science and engineering applic…
