2 MAE 142 State Space A state space model is formed by a collection of differential equations that predict the dynamic behavior of a system (or vehicle). The state vector includes variables that are needed to determine the system “state”. The state vector includes motion variables (position, velocity, …) … But also may include variables that describe the state of vehicle subsystems Engine → temperature, pressure, thrust, rpm Structural → deformation, stress Aerodynamics → unsteady effects Controls → surface deflections, momentum wheel speeds
