Dynamic model of non-linear system

AI Thread Summary
Linearization of non-linear systems, such as a DC-DC converter, is crucial for simplifying analysis and control design, allowing for easier understanding of system dynamics. The process involves approximating the non-linear system around a specific operating point by adding small perturbations, which helps in predicting system behavior under small deviations. This approach is essential because it transforms complex non-linear equations into linear ones, making them more manageable for analysis. Engaging with foundational resources, like Wikipedia, can provide a clearer understanding of these concepts and lead to more specific inquiries. A solid grasp of linearization techniques is vital for effective modeling of non-linear systems.

i am finding it difficult to get insight about modelling of non linear system (electrical).
my queries are,
consider the system is DC DC converter...
1) I read that to study the dynamics of the system we linearise the non-linear system...why do we want to linearise it?...
2)can some one please explain me the process of linearisation clearly...why do we want to add perturbation to the operating point...

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...
