摘要: 提出一种空间操控任务控制仿真平台设计方案,具有通用性强、任务组建速度快、操控过程模拟逼真度高等特点。平台采用FMI实现多源模型耦合,通过Python脚本进行任务控制,基于Unity3D实现虚拟视景仿真,通过配置工具建立复杂空间操控机构的虚拟场景模型与数字仿真模型变量的映射,提高了平台的通用性和可扩展性。以典型在轨维护机械臂抓捕过程为例,进行了仿真验证。

Abstract: The design of simulation platform for space mission operations is investigated. The platform has the advantages of high generality and extensibility, being easy to build up new task. FMI (Functional Mockup Interface) standard is adopted to achieve integration of multisource models, and Python scripts are used to realize the task schedule. Unity3D is adopted to implement the visual display system which could display space manipulation process with high fidelity 3D virtual scenes. Configuration tool is developed to map the 3D objects in visual scene with simulation physical variables for complex space control mechanism, which greatly improves the platform's generality and extensibility. Finally a typical space operation mission of capturing an on-orbit target by deployed robotic arm is taken to demonstrate the functions of the platform.

Key words: space operation, simulation system, visual display, FMI standard
