摘要: 针对助飞鱼雷铰链力矩时变且变化范围大的特点,设计了符合产品要求的电动舵回路系统,建立了该系统的数学模型。根据一条典型标准弹道,计算出铰链力矩的变化规律,施加在电动舵回路系统上,通过数学仿真方法开展舵负载对电动舵回路系统的性能影响研究。利用MATLAB/Simulink工具进行了数学仿真试验,得出了舵机工作在非线性区,如果发生反操纵现象,对舵回路系统的过渡过程影响很大,甚至会引起系统发散。其研究结果对控制半实物仿真方法研究、舵回路系统设计、调试以及随动式舵负载模拟器的设计与研制具有指导意义。Abstract: An electric steering fin actuator loop system(ESFALS) that meets the requirements for product was designed, and a mathematical model of this system was established based on the features of hinge moment varying with time in big amplitude scope. According to the hinge moment changing law of a typical standard trajectory, the influence of load on ESFALS performance was studied. Simulation results show that steering fin working in nonlinear area has significant effect on the transition period of ESFALS and causes system divergence in the case of anti-steering.
