基于BTT的反鱼雷鱼雷偏航角速率控制器设计

Design of Yaw Angular Velocity Controller for Anti-Torpedo Torpedo Based on Bank-to-Turn

反鱼雷鱼雷(ATT)的机动性对于其成功拦截来袭鱼雷的概率有着重要作用,而随着ATT机动性的提高,对其控制的难度也越来越大,这就对ATT的控制器设计提出了更高的要求。可以选用倾斜转弯(BTT)控制方式来提高ATT的机动性。研究了常规的比例-积分-微分(PID)控制,智能PID控制,预测函数控制(PFC)和模糊自适应PID控制,并将它们分别应用于ATT的偏航角速率控制。仿真结果表明,相对常规PID控制,智能PID控制、PFC和模糊PID控制时,系统控制过程平滑、无超调,系统响应快速、稳定、准确,且结果简单,实用性强。相比较而言,PFC相对智能PID控制和模糊PID控制响应速度更快,而且计算量小,更适应ATT偏航角速率控制系统的快速响应要求。

To enhance maneuverability of anti-torpedo torpedo（ATT）,a new yaw angular velocity controller for ATT is designed by analyzing and adopting conventional PID control,intelligent PID control,predictive functional control（PFC）,and fuzzy adaptive PID control,respectively based on bank-to-turn（BTT） control mode.Simulation results show that,com-pared with conventional PID control,intelligent PID control,PFC and fuzzy adaptive PID control make system control process smoother,faster and more accurate without overshoot.Particularly,PFC is more suitable for yaw angular velocity control of ATT because of its fastest response and least calculation.
