ye, lotsa shit in intro controls might've been the bees knees in the 50s, but long since useful for actual systems

...i only know about transfer functions...

what is a state-space representation?

ur talking about for a circuit, right?

>> No.4725112

state space representation is shit. go fuck yourself.

you can take any nth order ODE and represent it as a system of 1st order ODEs, this can be written in matrix form as
dx/dt = Ax + Bu

the output is written as y = Cx + Du

these two equations is what's called the state space representation of a system. x is the state vector , u is the input or control, y is the output.

i use transfer fcns cuz i can think about them in my dumb little head and it makes sense

lololol enjoy having no ability to bomb other countries, I'll be happy to send some V2 rockets, patriot missiles, predator drones, and ICBMs your way :)

T=CPhi(s)B

Transfer function can be obtained from state space. So what exactly is your point?
