Polynomial Constraints for Robustness Analysis of Nonlinear Systems
Neelay Junnarkar, Peter Seiler, Murat Arcak
This paper presents a framework for abstracting uncertain or non-polynomial components of dynamical systems using polynomial constraints. This enables the application of polynomial…
Fast Assignment in Asset-Guarding Engagements using Function Approximation
Neelay Junnarkar, Emmanuel Sin, Peter Seiler +2
This letter considers assignment problems consisting of n pursuers attempting to intercept n targets. We consider stationary targets as well as targets maneuvering toward an asset.…
Integral Quadratic Constraints with Infinite-Dimensional Channels
Aleksandr Talitckii, Peter Seiler, Matthew M. Peet
Modern control theory provides us with a spectrum of methods for studying the interconnection of dynamic systems using input-output properties of the interconnected subsystems. Per…
Robust Regret Optimal Control
Jietian Liu, Peter Seiler
This paper presents a synthesis method for robust, regret optimal control. The plant is modeled in discrete-time by an uncertain linear time-invariant (LTI) system. An optimal non-…
Structured Singular Value of a Repeated Complex Full-Block Uncertainty
Talha Mushtaq, Diganta Bhattacharjee, Peter Seiler +1
The structured singular value (SSV), or mu, is used to assess the robust stability and performance of an uncertain linear time-invariant system. Existing algorithms compute upper a…
Analysis of Gradient Descent with Varying Step Sizes using Integral Quadratic Constraints
Ram Padmanabhan, Peter Seiler
The framework of Integral Quadratic Constraints (IQCs) is used to perform an analysis of gradient descent with varying step sizes. Two performance metrics are considered: convergen…
Synthesis of Stabilizing Recurrent Equilibrium Network Controllers
Neelay Junnarkar, He Yin, Fangda Gu +2
We propose a parameterization of a nonlinear dynamic controller based on the recurrent equilibrium network, a generalization of the recurrent neural network. We derive constraints…
Revisiting PGD Attacks for Stability Analysis of Large-Scale Nonlinear Systems and Perception-Based Control
Aaron Havens, Darioush Keivan, Peter Seiler +2
Many existing region-of-attraction (ROA) analysis tools find difficulty in addressing feedback systems with large-scale neural network (NN) policies and/or high-dimensional sensing…
Robust Control Barrier Functions with Sector-Bounded Uncertainties
Jyot Buch, Shih-Chi Liao, Peter Seiler
This paper focuses on safety critical control with sector-bounded uncertainties at the plant input. The uncertainties can represent nonlinear and/or time-varying components. We pro…
Control Barrier Functions With Unmodeled Dynamics Using Integral Quadratic Constraints
Peter Seiler, Mrdjan Jankovic, Erik Hellstrom
This paper presents a control design method that achieves safety for systems with unmodeled dynamics at the plant input. The proposed method combines control barrier functions (CBF…
