As of 2025, the field is moving toward . Finite Element Models are too slow for flight computers. Instead, engineers are training Neural ODEs (Neural Ordinary Differential Equations) on FEM data to create reduced-order models (ROMs) that run at 1 kHz on flight hardware.

A typical multistage launch vehicle has a slenderness ratio of 10:1 to 20:1. During atmospheric flight, aerodynamic forces induce bending moments. If the vehicle's natural bending frequency dips below the control system bandwidth, the controller can inadvertently excite the structural modes rather than damp them. This phenomenon is known as control-structure interaction (CSI). As of 2025, the field is moving toward
