WebA minimum-phase system, whether discrete-time or continuous-time, has an additional useful property that the natural logarithm of the magnitude of the frequency response (the "gain" measured in nepers which is proportional to dB) is related to the phase angle of the … WebA nonlinear small phase theorem is then established for feedback stability analysis of semi-sectorial systems. Additionally, its generalized version is proposed via the use of multipliers. These nonlinear small phase theorems generalize a version of the classical passivity theorem and a recently appeared linear time-invariant small phase theorem.

WebThe small gain theorem is one of the most important results in the theory of robust control. It lays the foundation for the traditional gain-based analysis and synthesis, especially within the H∞ control paradigm. This entry is concerned with the small phase theorem, which … WebIn this talk, we start with two definitions of matrix phase and present two corresponding versions of the small phase theorem. Our current study shows that we can even extend the concept of phase and the small phase theorem to nonlinear systems and much beyond. … florian foods

http://ifatwww.et.uni-magdeburg.de/ifac2024/media/pdfs/4488.pdf WebThis paper proposes an overall practical stability assessment for a multi-port single-phase solid-state transformer (MS3T) in the electromagnetic timescale. When multiple stable subsystems are combined into one MS3T, the newly formed MS3T has a certain possibility to be unstable. Thus, this paper discusses the stability assessment of the MS3T in detail. … WebMar 16, 2024 · The initial configuration fills a region of phase space that includes a particle at rest at the origin (lower left corner of the shaded shape. This initial region includes a small initial displacement (up to approximately Δx) as well as a small initial momentum (up to approximately Δp). florian forsch
