Cluster-Based Distributed Small-Signal Stability Certificates for Grid-Forming Inverter Networks
Bhathiya Rathnayake, Sijia Geng
Large-scale power networks are often organized by geography, ownership, or control authority, making stability certificates that require a fully assembled global model challenging.…
Grid-Forming Control with Assignable Voltage Regulation Guarantees and Safety-Critical Current Limiting
Bhathiya Rathnayake, Sijia Geng
This paper develops a nonlinear grid-forming (GFM) controller with provable voltage-formation guarantees, with over-current limiting enforced via a control-barrier-function (CBF)-b…
Performance-Barrier Event-Triggered PDE Control of Traffic Flow
Peihan Zhang, Bhathiya Rathnayake, Mamadou Diagne +1
For stabilizing stop-and-go oscillations in traffic flow by actuating a variable speed limit (VSL) at a downstream boundary of a freeway segment, we introduce event-triggered PDE b…
Setpoint Tracking and Disturbance Attenuation for Gas Pipeline Flow Subject to Uncertainties using Backstepping
Bhathiya Rathnayake, Anatoly Zlotnik, Svetlana Tokareva +1
In this paper, we consider the problem of regulating the outlet pressure of gas flowing through a pipeline subject to uncertain and variable outlet flow. Gas flow through a pipe is…
Performance-Barrier Event-Triggered Control of a Class of Reaction-Diffusion PDEs
Bhathiya Rathnayake, Mamadou Diagne, Jorge Cortes +1
We employ the recent performance-barrier event-triggered control (P-ETC) for achieving global exponential convergence of a class of reaction-diffusion PDEs via PDE backstepping con…
Output Feedback Periodic Event-Triggered and Self-Triggered Boundary Control of Coupled Linear Hyperbolic PDEs
Eranda Somathilake, Bhathiya Rathnayake, Mamadou Diagne
In this paper, we expand recently introduced observer-based periodic event-triggered control (PETC) and self-triggered control (STC) schemes for reaction-diffusion PDEs to boundary…
Observer-based Periodic Event-triggered and Self-triggered Boundary Control of a Class of Parabolic PDEs
Bhathiya Rathnayake, Mamadou Diagne
This paper introduces the first observer-based periodic event-triggered control (PETC) and self-triggered control (STC) for boundary control of a class of parabolic PDEs using PDE…
Event-triggered Boundary Control of a Class of Reaction-Diffusion PDEs with Time-dependent Reactivity
Bhathiya Rathnayake, Mamadou Diagne
This paper presents an event-triggered boundary control strategy for a class of reaction-diffusion PDEs with time-varying reactivity under Robin actuation. The control approach con…
Observer-based Event-triggered Boundary Control of the One-phase Stefan Problem
Bhathiya Rathnayake, Mamadou Diagne
This paper provides an observer-based event-triggered boundary control strategy for the one-phase Stefan problem using the position and velocity measurements of the moving interfac…
Sampled-Data and Event-triggered Boundary Control of a Class of Reaction-Diffusion PDEs with Collocated Sensing and Actuation
Bhathiya Rathnayake, Mamadou Diagne, Iasson Karafyllis
This paper provides observer-based sampled-data and event-triggered boundary control strategies for a class of reaction-diffusion PDEs with collocated sensing and Robin actuation.…
Observer-based Event-triggered Boundary Control of a Class of Reaction-Diffusion PDEs
Bhathiya Rathnayake, Mamadou Diagne, Nicolas Espitia +1
This paper presents an observer-based event-triggered boundary control strategy for a class of reaction-diffusion PDEs with Robin actuation. The observer only requires boundary mea…
