Consider, I have a dynamic system model for air compressor. Which means I have modelled the system by including its physics. Does this means I also included the transients of the system?
What I think is, when i modelled any system with equations, I think that includes the transients. Is it...

What does it mean when the viscous drag is parallel to the axis of rotation?
It also turns out that this system needs two equations. I...

Deriving an s-domain equation for the following inputs a) &b)
3. The Attempt at a Solution
I understand how to derive the equation for an input with zero initial conditions (part a) but I'm not sure what to do when there are non-zero initial conditions (part b)
I would like to ask why cannot I think G5 in series with G3(G4+G6G7) and then after muliplying them why I cannot think of G5*G3(G4+G6G7) in parallel to G2 so sum G2 and G5*G3(G4+G6G7) ?
Thank you.

Can someone please explain intuitively how the terms “frequency” and “dynamics” are related ? I understand the concept of each of these two individually, but I am having some difficulty visualizing what high-frequency dynamics mean.

Hi all,
I would like to know why the Transfre function of the system is represented in S Domain instead of doing all the math in time domain itself. I studied a course on control systems and i wonder why s- domain is taken instead of other domains like Z- domain and others.
Please refer belwo...
I am trying to calculate the steady state error of the following system but unable to do it. I have used MATLAB and calculated the steady state error to be 0.1128 but don't understand the steps that I need to do to calculate this.
Please help.
