Dissipativity-Based Decentralized Co-Design of Distributed Controllers and Communication Topologies for Vehicular Platoons

1 code implementation11 Dec 2023 Shirantha Welikala, Zihao Song, Panos J. Antsaklis, Hai Lin

However, it is beneficial to design both the platooning controller and the communication topology simultaneously, i. e., controller and topology co-design, especially in the cases of platoon splitting and merging.

Smooth Robustness Measures for Symbolic Control Via Signal Temporal Logic

no code implementations16 May 2023 Shirantha Welikala, Hai Lin, Panos J. Antsaklis

Moreover, the degree of satisfaction of STL specifications can be evaluated using ``STL robust semantics'' as a scalar robustness measure.

Decentralized and Compositional Interconnection Topology Synthesis for Linear Networked Systems

no code implementations4 May 2023 Shirantha Welikala, Hai Lin, Panos J. Antsaklis

In this paper, we consider networked systems comprised of interconnected sets of linear subsystems and propose a decentralized and compositional approach to stabilize or dissipativate such linear networked systems via optimally modifying some existing interconnections and/or creating entirely new interconnections.

Centralized and Decentralized Techniques for Analysis and Synthesis of Non-Linear Networked Systems

no code implementations29 Sep 2022 Shirantha Welikala, Hai Lin, Panos J. Antsaklis

Second, we show that the centralized interconnection topology \emph{synthesis} techniques for these NSCs can also be developed as LMI problems.

Distributed Adaptive Backstepping Control for Vehicular Platoons with Mismatched Disturbances Using Vector String Lyapunov Functions

no code implementations5 Jul 2022 Zihao Song, Shirantha Welikala, Panos J. Antsaklis, Hai Lin

Using this notion, we propose an adaptive backstepping controller for the platoon such that the compositionality and the distributed nature of the controller can be ensured while the internal stability and string stability of the closed-loop system are formally guaranteed.

On-line Estimation of Stability and Passivity Metrics

no code implementations31 Mar 2022 Shirantha Welikala, Hai Lin, Panos J. Antsaklis

We consider the problem of on-line evaluation of critical characteristic parameters such as the L_2-gain (L2G), input feedforward passivity index (IFP) and output feedback passivity index (OFP) of non-linear systems using their input-output data.

Robust Approximate Simulation for Hierarchical Control of Piecewise Affine Systems under Bounded Disturbances

no code implementations4 Mar 2022 Zihao Song, Vince Kurtz, Shirantha Welikala, Panos J. Antsaklis, Hai Lin

First, a lower-dimensional linear system (abstraction) and an associated interface are designed to enable the output of the PWA system (concrete system) to track the output of the abstraction.

Resilient Learning-Based Control for Synchronization of Passive Multi-Agent Systems under Attack

no code implementations28 Sep 2017 Arash Rahnama, Panos J. Antsaklis

We define a general Byzantine attack on the event-triggered multi-agent network system and characterize its negative effects on synchronization.
