为反映航天器系统涉及的多学科交互作用下的控制特性,开发了包含机械、电气、控制、软件等的多领域统一建模与仿真平台.该平台包含姿控软件、飞轮系统(电机及其驱动器、轴承摩擦、飞轮机构等)、磁力矩器、姿态敏感器、姿态动力学、轨道动力学、环境力矩等不同领域的模块,各模块由Modelica语言实现,有机集成一体.对两种典型的姿态控制模式——姿态建立及姿态机动的仿真表明,利用该仿真平台不但可分析整个系统的闭环控制性能,还可评估各领域部件对整体性能的影响.在航天器研制的各个阶段(方案、子系统、系统等)充分使用该平台,可实现多学科设计优化的目标.
In order to reflect the control characteristics under the multidisciplinary interaction of spacecraft systems, a multi-domain unified modeling and simulation platform including mechanical, electrical, control, software and so on has been developed. The platform includes attitude control software, flywheel system Drive, bearing friction, flywheel mechanism, etc.), magnetometer, attitude sensor, attitude dynamics, orbit dynamics, environmental torque and other different areas of the module, the Modelica language by the module, the organic integration of the two typical Attitude Control Mode - The simulation of attitude establishment and attitude maneuver shows that the simulation platform can not only analyze the closed-loop control performance of the whole system, but also evaluate the impact of components in various fields on the overall performance.In the various stages of spacecraft development (program, Subsystems, systems, etc.) make full use of this platform to achieve the goal of multidisciplinary design optimization.
