   Inversion-based Control Simplifications for a Cycling-mode Power Converter in Particle Accelerators
By Amel BAZIZ, Dimitris XYSTRAS, Gilles LE GODEC, Philippe DELARUE, Alain BOUSCAYROL [View]
[Download]

Abstract: This paper analyzes control simplifications for a high-accuracy power converter with energy recovery capability used to supply electromagnets in particle accelerators. The Energetic Macroscopic Representation (EMR) graphical formalism is used to organize the system model and its control, which are validated through simulation and experimental results. The results indicate that achieving high accuracy for the magnet current using cascaded PI controllers necessitates a full control structure with the maximum number of measurements and control actions, at cost of additional sensors and complex implementation. Although control structure simplifications compromise accuracy specifications, the controllability remains ensured.

   Minimization of the circulating currents of an interleaved converter for particle accelerator using inversion-based control
By Gabriel GODART, Fulvio BOATTINI, Philippe DELARUE, Alain BOUSCAYROL [View]
[Download]

Abstract: An interleaved DC/DC converter is used to supply a magnet for particle accelerator.A very high accuracy of 50 parts per million is required to control the particle beam. Any disturbance can reduce this accuracy. An inversion-based control is derived from the Energetic Macroscopic Representation of this power converter.This control is composed of several control loops and compensations. The control leads to the right accuracy despite some ripple due to current measurement.
