Description
The dynamics of an RF cavity control system can be modeled with a great deal of accuracy. This includes the dynamics of the cavity, beam+cavity interactions, microphonics, Lorentz-Force Detuning, the field control loop, and the tuning control loop. A time-domain simulator has been developed in Python to study the behavior of a complete RF control system with respect to varying feedback configurations, different controller types and control algorithms, and different operational conditions. Regarding field control: a comparison between traditional PID controllers, Active Disturbance Rejection Controllers (ADRCs), and Linear-Quadratic Regulators (LQRs) is performed. Metrics such as disturbance rejection, stability, peak power, and cavity field amplitude and phase transients are used to evaluate the performance of the controllers. A similar process is carried out for cavity tuning control loops.
