Research on the control over underwater high-speed projectiles based on thrust vector

Due to the shortage of the fins of the underwater high-speed projectile which can cause cavitation itself, the authors propose to use cavitator and thrust vector to control its movement. Firstly, its non-linear mathematical model was linearized and then its depth state space model was got. Secondly, controllers of the system were designed by use of the robust pole placement algorithm and the optimal control algorithm and then they were simulated and analyzed. The simulation results show that the system＇s dynamic property has distinct improvement and the optimal control algorithm has more superior performance in the system depth control.
