Resumen:
We describe the design and implementation of anH∞ controller for PTB?s 14-bit cryogenic current comparator(CCC). Measurement results obtained using either the newlyimplemented digital H∞ controller or the conventional analogintegrator are consistent. In a wide frequency range, the system?snoise figure is improved when using the new controller.Index Terms ? Current comparator, electrical resistancemeasurement, H∞ control, system identification, superconductingquantum interference device (SQUID).
