Controllability Analysis of Longitudinal Canard-based Sounding Rocket Dynamics at Certain Flight Conditions

A rocket is an aviation vehicle that flies along a specific trajectory to accomplish its mission. Several missions include delivering people to the ISS in space, putting a satellite into orbit, monitoring atmospheric conditions, and conducting military and defense missions. A rocket must be stable on its trajectory to accomplish those various missions. A precise dynamic model of a sounding rocket is required to obtain precise prediction flight experiments. Previous studies have shown that some linear models constructed from the linearizing nonlinear model of canard-based sounding rockets on certain flight conditions accurately represent the rocket dynamic. However, the study was performed without conducting the controllability analysis. Controllability is a crucial aspect of rocket flight dynamics as it refers to the rocket's ability to be controlled by its control systems. This paper aims to confirm the experimental results from a previous study about whether the linear model of the canard-based sounding rocket is controllable or uncontrollable.
