    Application of robust control to a cryogenic current comparator
    (2016-07) Bierzychudek, Marcos E.; Götz, Martin; Sánchez-Peña, Ricardo; Tonina, Alejandra; Iuzzolino, Ricardo; Drung, Dietmar
    "We describe the design and implementation of an H ∞ controller for PTB's 14-bit cryogenic current comparator (CCC). Measurement results obtained using either the newly implemented digital H ∞ controller or the conventional analog integrator are consistent. In a wide frequency range, the system's noise figure is improved when using the new controller."

    Application of robust control to a cryogenic current comparator
    (2017-06) Bierzychudek, Marcos E.; Götz, Martin; Sánchez-Peña, Ricardo; Iuzzolino, Ricardo; Drung, Dietmar
    "This paper describes the implementation of a digital robust controller in a cryogenic current comparator. The controller was designed applying H∞ control theory and it was programmed in a home-made digital unit. Experimental comparisons of the new robust controller with the conventional analog integrator have showed a significant improvement of stability robustness and noise rejection in the system."
