标题： Estimation of superconducting cavity bandwidth and detuning using a Luenberger observer

摘要： 得益于超导技术的进步，未来十年将出现几台连续波线性加速器。 对于这些机器，跟踪主要腔体参数（如谐振器带宽和失谐）至关重要。 带宽提供了关于腔体超导状态的信息。 失谐应尽可能减小，以限制运行腔体所需的功率。 这些参数的估计通常在低能射频控制系统数字电子设备中实现，以最小化计算延迟。 在本文中，我们提出了一种使用Luenberger观测器计算带宽和失调的方法。 与之前的方法不同，状态观测器在原生控制系统采样率下提供估计值，而无需显式过滤输入信号。 此外，可以通过调整增益参数直观地控制估计值的误差收敛特性。 本文中介绍了所推导观测器的实现考虑因素和测试结果。 显示英文摘要

摘要： Enabled by progress in superconducting technology, several continuous wave linear accelerators are foreseen in the next decade. For these machines, it is of crucial importance to track the main cavity parameters, such as the resonator bandwidth and detuning. The bandwidth yields information on the superconducting state of the cavity. The detuning should be minimized to limit the required power to operate the cavity. The estimation of these parameters is commonly implemented in the digital electronics of the Low-Level RF control system to minimize the computation delay. In this proceeding, we present a way to compute the bandwidth and detuning using a Luenberger observer. In contrast to previous methods, a state observer yields estimations at the native control system sample rate without explicitly filtering the input signals. Additionally, the error convergence properties of the estimations can be controlled intuitively by adjusting gain parameters. Implementation considerations and test results on the derived observer are presented in the manuscript.
