Certificate-based Synthesis of Coordinated Droop Control for Heterogeneous Radial Distribution Networks
Georgios Pantazis, Michelle Chong
Voltage certificates for droop-controlled low voltage feeders are often constructed from global worst-case quantities. In heterogeneous feeders, such bounds can hide where voltage…
Data-driven Reachable Set Estimation with Tunable Adversarial and Wasserstein Distributional Guarantees
Georgios Pantazis, Michelle S. Chong
We study finite horizon reachable set estimation for unknown discrete-time dynamical systems using only sampled state trajectories. Rather than treating scenario optimization as a…
Secondary Controller Design for the Safety of Nonlinear Systems via Sum-of-Squares Programming
Yankai Lin, Michelle S. Chong, Carlos Murguia
We consider the problem of ensuring the safety of nonlinear control systems under adversarial signals. Using Lyapunov based reachability analysis, we first give sufficient conditio…
Controller confidentiality for nonlinear systems under sensor attacks
Michelle S. Chong
Controller confidentiality under sensor attacks refers to whether the internal states of the controller can be estimated when the adversary knows the model of the plant and control…
A secure state estimation algorithm for nonlinear systems under sensor attacks
Michelle S. Chong, Henrik Sandberg, Joao P. Hespanha
The state estimation of continuous-time nonlinear systems in which a subset of sensor outputs can be maliciously controlled through injecting a potentially unbounded additive signa…
Adaptive voltage regulation of an inverter-based power distribution network with a class of droop controllers
Michelle S. Chong, Henrik Sandberg
The voltage received by each customer connected to a power distribution line with local controllers (inverters) is regulated to be within a desired margin through a class of slope-…
