半实物仿真是导弹飞控系统研制过程中的必要环节，各仿真设备的误差对于仿真结果的影响不容忽视。借助于某型导弹半实物仿真系统的搭建，对影响仿真精度的各项主要误差进行了研究。通过理论推导建立了三轴转台、负载模拟台和数据采集的误差模型，与半实物仿真试验进行对比验证其有效性。最后，基于蒙特卡洛统计原理完成误差模型对仿真结果的影响分析。结果表明：各项误差模型能够满足仿真精度的分析要求，为类似半实物仿真系统的分析、测量和误差补偿提供理论依据。

Hardware-in-the-loop simulation is necessary for the development of missile?s flight control system. The influence of the simulation equipment errors to simulation results cannot be ignored. Referring to the construction of hardware-in-the-loop( HIL) simulation system for a certain missile, major errors which mostly affect the precision of simulation are studied. Through theoretical derivation, the error models of three-axis rotary table, load simulator and data acquisition are established. The validity of the these models is verified by contrast with HIL simulation test results. Finally, the influence of errors on simulation results is confirmed based on Monte-Carlo method. The experimental results show that each error model can meet the demand of the simulation accuracy analysis which extends theory basis for analysis, measurement and error compensation for suchlike HIL simulation systems.
