Low-Latency Digital Downconversion for Control Applications
Olof Troeng, Lawrence Doolittle
The slowly varying complex envelope of sinusoidal signals can be estimated in real-time using digital downconversion. In this paper, we discuss the requirements on digital downconv…
Modeling same-order modes of multicell cavities
Olof Troeng
We derive the transfer function of a multicell cavity with parasitic same-order modes (from power coupler to pickup probe). The derived model is discussed and compared to measureme…
Energy-based parameterization of accelerating-mode dynamics
Olof Troeng
We propose a parameterization of the accelerating-mode dynamics of accelerating cavities in terms of energy, power, and current. This parameterization avoids many confusing feature…
Five-Full-Block Structured Singular Values of Real Matrices Equal Their Upper Bounds
Olof Troeng
We show that the structured singular value of a real matrix with respect to five full complex uncertainty blocks equals its convex upper bound. This is done by formulating the equa…
A Refined Algorithm for Curve Fitting by Segmented Straight Lines
Olof Troeng, Mattias Fält
We consider least squares approximation of a function of one variable by a continuous, piecewise-linear approximand that has a small number of breakpoints. This problem was notably…
