摘要
为提高靶场试验中修正组件的打击精度,获得更好的滚转控制效果,评估滚转控制算法和弹道修正策略的性能,建立具有实际指导意义的双旋弹丸弹道修正弹修正组件控制响应模型,提出了一种数值仿真与试验测试相结合的执行机构建模方法.该方法通过获取双旋执行机构在阶跃冲击下的时域响应特性,结合拉氏变换计算传递函数,建立电磁控制力矩动态响应模型;通过飞行试验进一步获得准确的气动力矩和隔转阻尼力矩模型,建立了双旋弹道修正组件固定鸭舵滚转控制响应模型.风洞环境下的控制试验结果表明:双旋弹丸弹道修正组件控制响应模型能够以较高的精度评估组件动态控制响应特性,误差小于1.5%.试验验证了建模方法的可行性,也为后续弹道修正策略和控制算法研究提供了精确可靠的分析模型.
In order to improve the attacking accuracy of the firing range test,an actuator roll control response model of the dual-spin trajectory correction projectile was built,to get the realtime control effect within the whole trajectory and evaluate the performance of different control algorithms and trajectory correction strategies.An actuator modeling method was proposed based on numerical simulation and experimental tests.The time-domain response characteristics under the step impact were recorded to conduct the transfer function analysis with the（inverse）Laplace transformation so that the dynamic electromagnetic torque model could be established.Based on experimental data in combination with the numerical simulation,the accurate aerodynamic and damping moment model was built,thus,the overall control response prediction model was established.It is shown by the roll control experiments in the wind tunnel that the established system model is able to predict the actual dynamic responding performance with a high degree of accuracy（less than 1.5%）.The method for system modeling is proved to be feasible and provides an accurate and reliable analysis model for future research.
