Invariant Set Estimation for Piecewise Affine Dynamical Systems Using Piecewise Affine Barrier Function

no code implementations6 Feb 2024 Pouya Samanipour, Hasan A. Poonawala

The invariant set of PWA dynamical system is estimated using ReLU networks or its equivalent PWA function.

Automated Stability Analysis of Piecewise Affine Dynamics Using Vertices

no code implementations8 Jul 2023 Pouya Samanipour, Hasan A. Poonawala

We parametrize the Lyapunov function as a PWA function, with polytopic regions defined by the PWA dynamics.

Provably Correct Sensor-driven Path-following for Unicycles using Monotonic Score Functions

no code implementations21 Mar 2023 Benton Clark, Varun Hariprasad, Hasan A. Poonawala

This paper develops a provably stable sensor-driven controller for path-following applications of robots with unicycle kinematics, one specific class of which is the wheeled mobile robot (WMR).

Robust Control for Dynamical Systems With Non-Gaussian Noise via Formal Abstractions

1 code implementation4 Jan 2023 Thom Badings, Licio Romao, Alessandro Abate, David Parker, Hasan A. Poonawala, Marielle Stoelinga, Nils Jansen

This iMDP is, with a user-specified confidence probability, robust against uncertainty in the transition probabilities, and the tightness of the probability intervals can be controlled through the number of samples.

Sampling-Based Robust Control of Autonomous Systems with Non-Gaussian Noise

no code implementations25 Oct 2021 Thom S. Badings, Alessandro Abate, Nils Jansen, David Parker, Hasan A. Poonawala, Marielle Stoelinga

We use state-of-the-art verification techniques to provide guarantees on the iMDP, and compute a controller for which these guarantees carry over to the autonomous system.

Correct-by-construction reach-avoid control of partially observable linear stochastic systems

1 code implementation3 Mar 2021 Thom Badings, Hasan A. Poonawala, Marielle Stoelinga, Nils Jansen

By construction, any policy on the abstraction can be refined into a piecewise linear feedback controller for the LTI system.
