A Convex Optimization Approach to Compute Trapping Regions for Lossless Quadratic Systems

Authors: Shih-Chi Liao, A. Leonid Heide, Maziar S. Hemati, Peter J. Seiler

Publication under preparation.

This paper focuses developed convex-optimization-based method to verify the boundedness of solutions to Lossless Quadratic ODEs. This convex formulation provides wide connection to literature in modeling, analysis, and design in control and dynamical system using convex methods.

Quadratic Constraints for Local Stability Analysis of Quadratic Systems

Authors: Shih-Chi Liao, Maziar S. Hemati, Peter Seiler

Published in 2022 IEEE 61st Conference on Decision and Control (CDC), 2022

This paper proposes new quadratic constraints (QCs) to characterize a quadratic polynomial. Such QCs can be used in dissipation inequalities to analyze the stability and performance of nonlinear systems with quadratic vector fields.

Robust Control Barrier Functions with Sector-bounded Uncertainties

Authors: Jyot Buch, Shih-Chi Liao, Peter Seiler

Published in IEEE Control Systems Letters, 2021

This paper focuses on safety-cirical control under uncertainties. Robust control barrier functions are proposed, and convex optimization problem are formulated to ensure the safety of the uncertain system.
