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…
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…
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…
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…
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…
