Nettet13. okt. 2024 · The typical steps followed to linearise the system ˙x = f(x, u) is to split the state variable into two parts; a steady part (operating point) and a small-signal part. … Nettetthe model behaves: we sometimes talk about looking at the qualitative dynamics of a system. Equilibrium points– steady states of the system– are an important feature that we look for. Many systems settle into a equilibrium state after some time, so they might tell us about the long-term behavior of the system.
