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…
Multi-Array Electron Beam Stabilization using Block-Circulant Transformation and Generalized Singular Value Decomposition
Idris Kempf, Stephen R. Duncan, Paul J. Goulart +1
We introduce a novel structured controller design for the electron beam stabilization problem of the UK's national synchrotron light source. Because changes to the synchrotron will…
Symmetry Exploitation in Orbit Feedback Systems of Synchrotron Storage Rings
Idris Kempf, Paul J. Goulart, Stephen R. Duncan +1
Structural symmetries in the storage ring of synchrotrons are intentionally created during the design phase of the magnetic lattices, but they are not considered in the design of c…
Fast Gradient Method for Model Predictive Control with Input Rate and Amplitude Constraints
Idris Kempf, Paul Goulart, Stephen Duncan
This paper is concerned with the computing efficiency of model predictive control (MPC) problems for dynamical systems with both rate and amplitude constraints on the inputs. Inste…
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…
