Logarithmically Completely Monotonic Rational Functions
Hamed Taghavian, Ross Drummond, Mikael Johansson
This paper studies the class of logarithmically completely monotonic (LCM) functions. These functions play an important role in characterising externally positive linear systems wh…
Constrained optimal control of monotone systems with applications to battery fast-charging
Ross Drummond, Nicola E. Courtier, David A. Howey +2
Enabling fast charging for lithium ion batteries is critical to accelerating the green energy transition. As such, there has been significant interest in tailored fast-charging pro…
Bounding the difference between model predictive control and neural networks
Ross Drummond, Stephen R. Duncan, Matthew C. Turner +2
There is a growing debate on whether the future of feedback control systems will be dominated by data-driven or model-driven approaches. Each of these two approaches has their own…
Regional Stability Analysis of Transitional Fluid Flows
Leonardo F. Toso, Ross Drummond, Stephen R. Duncan
A method to bound the maximum energy perturbation for which regional stability of transitional fluid flow models can be guaranteed is introduced. The proposed method exploits the f…
Cell-Level State of Charge Estimation for Battery Packs Under Minimal Sensing
Dong Zhang, Luis D. Couto, Ross Drummond +2
This manuscript presents an algorithm for individual Lithium-ion (Li-ion) battery cell state of charge (SOC) estimation in a large-scale battery pack under minimal sensing, where o…
Reduced-Order Neural Network Synthesis with Robustness Guarantees
Ross Drummond, Mathew C. Turner, Stephen R. Duncan
In the wake of the explosive growth in smartphones and cyberphysical systems, there has been an accelerating shift in how data is generated away from centralised data towards on-de…
Structural Identifiability of a Pseudo-2D Li-ion Battery Electrochemical Model
Ross Drummond, Stephen R. Duncan
Growing demand for fast charging and optimised battery designs is fuelling significant interest in electrochemical models of Li-ion batteries. However, estimating parameter values…
Robust error bounds for quantised and pruned neural networks
Jiaqi Li, Ross Drummond, Stephen R. Duncan
With the rise of smartphones and the internet-of-things, data is increasingly getting generated at the edge on local, personal devices. For privacy, latency and energy saving reaso…
Resolving Kirchhoff's laws for state-estimator design of Li-ion battery packs connected in parallel
Ross Drummond, Luis D. Couto, Dong Zhang
A state-space model for Li-ion battery packs with parallel connected cells is introduced. The key feature of this model is an explicit solution to Kirchhoff's laws for parallel con…
Accelerated Gradient Methods with Memory
Ross Drummond, Stephen Duncan
A set of accelerated first order algorithms with memory are proposed for minimising strongly convex functions. The algorithms are differentiated by their use of the iterate history…
Circuit Synthesis of Electrochemical Supercapacitor Models
Ross Drummond, Shi Zhao, David A. Howey +1
This paper is concerned with the synthesis of RC electrical circuits from physics-based supercapacitor models describing conservation and diffusion relationships. The proposed synt…
Low-Order Mathematical Modelling of Electric Double Layer Supercapacitors Using Spectral Methods
Ross Drummond, David A. Howey, Stephen R. Duncan
This work investigates two physics-based models that simulate the non-linear partial differential algebraic equations describing an electric double layer supercapacitor. In one mod…
