车载捷联三轴视线稳定平台半实物仿真研究

Research of Hardware-in-loop Simulation for Vehicle-borne Strap-down 3 Axes Line-of-sight Stabilization Platform

由于车载捷联视线稳定平台系统的实车验证试验成本过高,因此有必要采用其它方法进行开发阶段的方案论证和系统验证。基于试验车辆实测的路面激励数据,构建了由三轴稳定平台子系统、仿真计算机子系统和台体姿态采集子系统等组成的车载捷联三轴视线稳定试验验证系统,并完成了半实物仿真验证试验。试验结果表明,该系统较好的模拟了多种路面下的车载捷联稳定平台视线稳定过程,验证了车载捷联稳定平台动力学模型及控制算法有效性。

The cost and risks associate with the vehicle-borne strap-down line-of-sight(LOS) stabilization platform system require that the system performance need to be validated on a real vehicle.A verification system of vehicle-borne strap-down 3 axes LOS stabilization platform system was developed,which consisted of three axes stabilization platform subsystem,simulation computer subsystem,data acquisition subsystem of attitude on a basis of road incentive data tested by vehicle,and then the ground test was accomplished.Test results indicate that this system can reflect the performance well for vehicle-borne strap-down LOS stabilization platform system under multi-style road,and the dynamic model and LOS stabilization algorithm of vehicle-borne strap-down 3 axes line-of-sight stabilization platform was validated effectiveness.
