How can the order of a transfer function be derived from its equivalent state space represen...

Suppose I have a discrete state space model: \begin{align} \theta[k+1] &= A \theta[k] + B u[k]\\ y[k] &= C \theta[k] \end{align} I know that the equivalent transfer function can be found by solving …

Why is my discretized transfer function unstable when my discretized state-space model is st...

I am working with a 30-state, 14-input linear model that is described by a state-space model: model_state_space = ss(A, B, C, D); The model is extremely slow (it describes the thermal behavior of a …
