Sensor Placement Strategies for Some Classes of Nonlinear Dynamic Systems via Lyapunov Theory
Sebastian Nugroho, Ahmad F. Taha
In this paper, the problem of placing sensors for some classes of nonlinear dynamic systems (NDS) is investigated. In conjunction with mixed-integer programming, classical Lyapunov…
Robust Dynamic State Estimation of Synchronous Machines with Asymptotic State Estimation Error Performance Guarantees
Sebastian Nugroho, Ahmad F. Taha, Junjian Qi
A robust observer for performing power system dynamic state estimation (DSE) of a synchronous generator is proposed. The observer is developed using the concept of $\mathcal{L}_{\i…
State Estimation in Water Distribution Networks through a New Successive Linear Approximation
Shen Wang, Ahmad F. Taha, Lina Sela +2
State estimation (SE) of water distribution networks (WDNs) is difficult to solve due to nonlinearity/nonconvexity of water flow models, uncertainties from parameters and demands,…
Receding Horizon Control for Drinking Water Networks: The Case for Geometric Programming
Shen Wang, Ahmad F. Taha, Nikolaos Gatsis +1
Optimal, network-driven control of Water Distribution Networks (WDN) is very difficult: valve and pump models form non-trivial, combinatorial logic; hydraulic models are nonconvex;…
Tuning-Free, Low Memory Robust Estimator to Mitigate GPS Spoofing Attacks
Junhwan Lee, Ahmad F. Taha, Nikolaos Gatsis +1
The operation of critical infrastructures such as the electrical power grid, cellphone towers, and financial institutions relies on precise timing provided by stationary GPS receiv…
Geometric Programming-Based Control for Nonlinear, DAE-Constrained Water Distribution Networks
Shen Wang, Ahmad F. Taha, Nikolaos Gatsis +1
Control of water distribution networks (WDNs) can be represented by an optimization problem with hydraulic models describing the nonlinear relationship between head loss, water flo…
