Missile’s Dynamical Modeling and BTT Decoupling Control

Missile’s nonlinear dynamics, linear model and actuator of X form model with 4 to 3 control surfaces conversion were proposed for BTT control. For the longitudinal, lateral and yaw channels, the optimal model track controllers were designed to satisfy 3 axis decoupling control requirements of BTT control of missiles. The designed feedback gain matrix elements were adjusted according H, command ny cand φ c. Nonlinear simulation illustrates the system can follow the command ny cand φ c in 0.5 second and side angel β is almost zero which offers a good base for BTT control design and realization.
