Roll Stability of ATT Based on BTT

Considering the disadvantages of STT (Skid-to-Turn) control technology, a kind of ATT (anti-torpedo torpedo) control technique based on BTT (Bank-to-Turn) is proposed. The roll maneuverability mathematics model of ATT is analyzed and predigested necessarily. The roll interference and control equations of ATT are established. Then the roll interference time course and roll angle rapidity are obtained. Finally, the configure method and result of roll control parameters are presented. And the transition curve of two types torpedo is analyzed through ensamples. The result of the research shows that, for the two types torpedo with roll control, the transition course of them is convergent. But, the latter is more appropriate for the demand of roll control system stability of ATT based on BTT, when the roll control parameters are presented in advance.
