Safe Output Regulation of Coupled Hyperbolic PDE-ODE Systems
Ji Wang, Miroslav Krstic
This paper presents a safe output regulation control strategy for a class of systems modeled by a coupled hyperbolic PDE-ODE structure, subject to fully distributed dis…
Safety Margins of Inverse Optimal ISSf Controllers
Ziliang Lyu, Yiguang Hong, Lihua Xie +1
We investigate the gain margin of a general nonlinear system under an inverse optimal input-to-state safe (ISSf) controller of the form u=u0(x)+u*(x,u0), where u0 is the nominal co…
Adaptive Override Control under High-Relative-Degree Nonovershooting Constraints
Ziliang Lyu, Miroslav Krstic, Kaixin Lu +2
This paper considers the problem of adaptively overriding unsafe actions of a nominal controller in the presence of high-relative-degree nonovershooting constraints and parametric…
Adaptive Certainty-Equivalence Control With Regulation-Triggered Finite-Time Least-Squares Identification, Part II: Analysis
Iasson Karafyllis, Miroslav Krstic
We present the stability analysis for the new regulation-triggered approach to adaptive control introduced in a companion paper. Due to the fact that the closed-loop system is hybr…
Adaptive Certainty-Equivalence Control With Regulation-Triggered Finite-Time Least-Squares Identification, Part I: Design
Iasson Karafyllis, Miroslav Krstic
For general nonlinear control systems we present a novel approach to adaptive control, which employs a certainty equivalence (indirect) control law and an identifier with event-tri…
