AI Thread Summary
Understanding the stability criteria for a transfer function involves analyzing Bode plots, root locus, and Nyquist plots. Each method offers different insights into system stability, with Bode plots focusing on gain and phase margins, root locus examining pole movements, and Nyquist providing a frequency response perspective. Conflicting information online can lead to confusion, highlighting the need for clear and consistent resources. Engaging with community members can help clarify these concepts. Mastery of these stability criteria is essential for effective control system design.

hi,

can anyone please help me with understanding the criteria for stability of a transfer function? especially with the bode plot, root locus, and nyquist.

i've gone through a few search results online and almost every site has different information that feels contradictory to me.

thanks,
bg742

Hi, Barney;
I can't help at all with your question, but I have a duty as a member of the Langauge Police. 'Criteria' is the plural; 'criterion' is the singular. :-p

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
