    "abstract": "The RF system for the SNS superconducting linac consists of a superconducting\ncavity, a klystron, and a low-level RF (LLRF) control system. For a proton\nlinac like SNS, the field in each individual cavity needs to be controlled to\nmeet the overall system requirements. The purpose of the LLRF control system is\nto maintain the RF cavity field to a desired magnitude and phase by controlling\nthe klystron driver signal. The Lorentz force detuning causes the shift of the\nresonant frequency during the normal operation in the order of a few hundreds\nhertz. In order to compensate the Lorentz force detuning effects, the cavity is\npre-tuned into the middle of the expected frequency shift caused by the Lorentz\nforce detuning. Meanwhile, to reduce the overshoot in the transient response, a\nfeed-forward algorithm, a linear parameter varying gain scheduling (LPV-GS)\ncontroller, is proposed to get away a repetitive noised caused by the pulsed\noperation as well as the Lorentz force detuning effects.",
