This is not an "introduction to state space models" video. You need to first talk about what does a state mean what does state space mean, why and where this model can be used etc. before diving right into the algebra behind the model.

Hi, how to identify the state variables in the state space models' equations ; means to know that which state of the system is being represented by the variables?
@apm
4 жыл бұрын
If you identify a state space model from data then the states have no physical realism. However, if you obtained the model from a physics-based model then the state corresponds to the original variable that you began with: apmonitor.com/pdc/index.php/Main/StateSpaceModel

The output equation is typically a condensed identity matrix with ones for the states that are measured. In this case it is y=x2 but it could also be y1=x1 and y2=x2 if both states are measured. In that case, it would be C=[1,0 ; 0,1]

Why is the function F(x,u) = 0 at "the nominal values" of x and u? What if F(x,u) = x^2 + u^2 + 1? Then F(x,u) will never equal zero, so why can we assume this to be zero? Also, you are taking a taylors approximation to make the nonlinear function F linear. But... does this assume that the derivatives of F are not linear? Rest of video is very, very well explained and clear though. Thank you.
@apm
5 жыл бұрын
Thanks for your question. It is zero because the nominal conditions are typically chosen at steady state conditions where the time derivatives are zero. dx/dt = 0 = F(x,u) please see this additional information on linearization: apmonitor.com/pdc/index.php/Main/ModelLinearization
