【摘要】 为了验证多体动力学环境下用户星天线开环回扫、扫描、自动跟踪中继卫星控制方案的可行性、软硬件集成的合理性,基于xPC建立了多体卫星地面半物理仿真系统,重点介绍了在xPC环境下,如何创建接口设备的驱动程序以建立xPC目标机与外部实物的数据交互。实时仿真结果表明了接口通信的正确性以及复合控制系统设计的合理性。更多还原

【Abstract】 To verify feasibility of the control strategy for user satellite antenna tracking and pointing relay satellite in the multi-mode dynamics simulation environment,and to test the real time performance of software and hardware of onboard computer,a hardware-in-the-loop simulation system is constructed based on xPC. Interface communication between xPC target computer and combined controller is demonstrated in detail.Real time simulation results show that the accuracy of interface model and the effectiveness of the combined control are well.更多还原
