Abstract

This paper presenting the modeling prediction and control of limit cycling behavior of a boosting rocket. The suspected source of nonlinear behavior is the presence of coulomb friction in the nozzle pivot mechanism. A classical sinusoidal describing function analysis is used to accurately observe the oscillatory characteristics. The limit cycling behavior is in turn, used to adjust control system parameters to indirectly control the oscillatory tendencies. Tradeoffs with guidance and control system stability / performance are also noted.
