Rolling Rate Control of High Maneuvering Rolling Airframe Missiles with Canard Configuration

对一种高机动鸭式布局导弹的旋转三通道转速控制方法进行了研究。分析了两对舵面布局的导弹滚转控制特性,发现鸭舵差动可产生相应的滚转控制力矩,4片舵面同时差动的滚转控制效率在不同滚转位置处的一致性较好。给出了双鸭舵实现纵侧向过载指令跟踪同时进行转速稳定的控制策略,以解决转速变化给导弹纵侧向控制带来不利影响的问题。考虑鸭舵滚转控制不确定性大,设计了基于模糊控制的转速稳定控制回路。仿真结果表明:提出的控制方法有较好的自适应能力和稳态跟踪精度,能解决旋转导弹转速控制面临的不确定性难题。研究对高机动旋转导弹的发展有一定的工程参考价值。

A rolling rate control method of high maneuvering rolling airframe missile with canard configuration and three channels was studied in this paper.The rolling control characteristics of the rolling airframe missile with two pairs of canard fins were analyzed.It found that the relevant rolling control moment could be produced by canard differential.The rolling control efficiencies at different positions were agreed well when 4 canards were differential at the same time.The control strategy of pitch,yaw and rolling rate was provided which avoided the negative effect of rolling rate change during maneuvering in the pitch or the yaw.To settle the uncertainty of rolling rate control,the fuzzy controller was adopted in rolling rate loop because of the uncertainness of the rolling control.The numerical simulation showed that the proposed method had well adaptive ability and steady tracking accuracy,which could solve the uncertainness problem in the missile's rolling rate control.The study is useful to the development of high maneuvering rolling airframe missiles in engineering.
