Feasibility of Simultaneous Input-Output Constraints for Tracking in a Class of LTI Systems: Part II
Junhyeok Yoon, Alan B. Cao, Heather Hussain +1
This paper illustrates the properties of a new CBF-governor that enables simultaneous input and output constraint satisfaction for a class of multi-input linear time-invariant syst…
Feasibility of Simultaneous Input-Output Constraints for Tracking in a Class of LTI Systems: Part I
Junhyeok Yoon, Heather Hussain, Anuradha M. Annaswamy
This paper addresses simultaneous input and output constraint satisfaction for a class of multi-input linear time-invariant systems with state feedback and integral action. A contr…
Closed-Loop Model-Based Control Barrier Functions with Application to Robust Flight Envelope Protection
Johannes Autenrieb, Mark Spiller, Peter A. Fisher +3
Ensuring operation of aerospace systems within prescribed flight envelope limits is a fundamental requirement for modern flight control architectures. Flight envelope protection ai…
Flight Envelope Protection for a Hypersonic Glide Vehicle Using Adaptive Safety-Critical Control
Johannes Autenrieb, Peter A. Fisher, Anuradha Annaswamy
This paper presents an adaptive safety-critical control framework for flight envelope protection (FEP) of hypersonic glide vehicles (HGVs) under model uncertainty. The proposed arc…
A Safe and Stable Controller for Fuel Cell Systems Using Adaptation and Reference Governors
Mychal Amoafo, Ilya Kolmanovsky, Anuradha Annaswamy
This paper proposes a control architecture integrating adaptation with Lyapunov-based Reference Governors (LRGs) to ensure state constraint satisfaction for first-order systems wit…
Adapt and Stabilize, Then Learn and Optimize: A New Approach to Adaptive LQR
Peter A. Fisher, Anuradha M. Annaswamy
This paper focuses on adaptive control of the discrete-time linear quadratic regulator (adaptive LQR). Recent literature has made significant contributions in proving non-asymptoti…
An Error-Based Safety Buffer for Safe Adaptive Control (Extended Version)
Peter A. Fisher, Johannes Autenrieb, Anuradha M. Annaswamy
We consider the problem of adaptive control of a class of feedback linearizable plants with matched parametric uncertainties whose states are accessible, subject to state constrain…
Adaptive Control of Dubins Vehicle in the Presence of Loss of Effectiveness (Extended Version)
Daniel Maldonado Naranjo, Anuradha M. Annaswamy
The control of a Dubins Vehicle when subjected to a loss of control effectiveness in the turning rate is considered. A complex state-space representation is used to model the vehic…
Analytical Construction of CBF-Based Safety Filters for Simultaneous State and Input Constraints (Extended Version)
Peter A. Fisher, Anuradha M. Annaswamy
We revisit the problem explored in [1] of guaranteeing satisfaction of multiple simultaneous state constraints applied to a single-input, single-output plant consisting of a chain…
