Neural Network Optimal Feedback Control with Guaranteed Local Stability

1 code implementation1 May 2022 Tenavi Nakamura-Zimmerer, Qi Gong, Wei Kang

The proposed architectures are compared against standard neural network feedback controllers through numerical simulations of two high-dimensional nonlinear optimal control problems: stabilization of an unstable Burgers-type partial differential equation, and altitude and course tracking for an unmanned aerial vehicle.

Neural network optimal feedback control with enhanced closed loop stability

no code implementations15 Sep 2021 Tenavi Nakamura-Zimmerer, Qi Gong, Wei Kang

In this paper we use numerical simulations to demonstrate that typical test accuracy metrics do not effectively capture the ability of an NN controller to stabilize a system.

QRnet: optimal regulator design with LQR-augmented neural networks

no code implementations11 Sep 2020 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.

Density Propagation with Characteristics-based Deep Learning

no code implementations21 Nov 2019 Tenavi Nakamura-Zimmerer, Daniele Venturi, Qi Gong, Wei Kang

Uncertainty propagation in nonlinear dynamic systems remains an outstanding problem in scientific computing and control.

Adaptive Deep Learning for High-Dimensional Hamilton-Jacobi-Bellman Equations

1 code implementation11 Jul 2019 Tenavi Nakamura-Zimmerer, Qi Gong, Wei Kang

In this paper, we propose a data-driven method to approximate semi-global solutions to HJB equations for general high-dimensional nonlinear systems and compute candidate optimal feedback controls in real-time.
