Control of Cross-Directional Systems using the Generalised Singular Value Decomposition
Idris Kempf, Paul J. Goulart, Stephen Duncan
Diamond Light Source produces synchrotron radiation by accelerating electrons to relativistic speeds. In order to maximise the intensity of the radiation, vibrations of the electro…
Control of Cross-Directional Systems with Approximate Symmetries
Idris Kempf, Paul Goulart, Stephen Duncan
Structural symmetries of linear dynamical systems can be exploited for decoupling the dynamics and reducing the computational complexity of the controller implementation. However,…
Model Predictive Control for Electron Beam Stabilization in a Synchrotron
Idris Kempf, Paul J. Goulart, Stephen R. Duncan
Electron beam stabilization in a synchrotron is a disturbance rejection problem, with hundreds of inputs and outputs, that is sampled at frequencies higher than kHz. In this f…
A Higher-Order Generalized Singular Value Decomposition for Rank Deficient Matrices
Idris Kempf, Paul J. Goulart, Stephen R. Duncan
The higher-order generalized singular value decomposition (HO-GSVD) is a matrix factorization technique that extends the GSVD to data matrices, and can be used to identif…
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…
ADMM for Block Circulant Model Predictive Control
Idris Kempf, Paul J. Goulart, Stephen Duncan
This paper deals with model predictive control problems for large scale dynamical systems with cyclic symmetry. Based on the properties of block circulant matrices, we introduce a…
