Model-Based and Data-Driven Hierarchical Control and Topology Co-Design for Robust Networked Systems
Shirantha Welikala, Zihao Song, Hai Lin +1
In this paper, we consider a class of networked systems comprising an interconnected set of linear subsystems, disturbance inputs, and performance outputs. Using dissipativity theo…
Dissipativity-Based Distributed Control and Communication Topology Co-Design for Nonlinear DC Microgrids
Mohammad Javad Najafirad, Shirantha Welikala
This paper presents a dissipativity-based distributed droop-free control and communication topology co-design framework for voltage regulation and current sharing in DC microgrids…
Dissipativity-Based Synthesis of Distributed Control and Communication Topology Co-Design for AC Microgrids
Mohammad Javad Najafirad, Shirantha Welikala, Lei Wu +1
This paper introduces a dissipativity-based framework for the joint design of distributed controllers and communication topologies in AC microgrids (MGs), providing robust performa…
Modeling PWM-Time-SOC Interaction in a Simulated Robot
Vidyut Pradeep, Shirantha Welikala
Accurate prediction of battery state of charge is needed for autonomous robots to plan movements without using up all available power. This work develops a physics and data-informe…
Funnel-Based Online Recovery Control for Nonlinear Systems With Unknown Dynamics
Zihao Song, Shirantha Welikala, Panos J. Antsaklis +1
In this paper, we focus on recovery control of nonlinear systems from attacks or failures. The main challenges of this problem lie in (1) learning the unknown dynamics caused by at…
