摘要:

随着空间探测与天文观测技术发展,航天器光学载荷对超精、超稳、超敏捷(三超)控制性能提出严苛要求。通过将大范围指向机构引入三超控制架构,能够解决大范围敏捷机动与超精超稳的技术矛盾,但也带来控制系统多级回路耦合及模态频率改变等问题。针对以上问题,建立了带有大范围指向机构的三超控制系统动力学模型,通过仿真分析表明指向机构的引入使载荷控制回路的低阶谐振峰频率上升,分析了指向机构控制带宽对系统动力学特性的影响,最后通过物理试验验证了分析结果,为三超平台控制器设计提供理论依据。

Abstract:

With the development of space exploration and astronomical observation technology, spacecraft optical payloads have put forward strict requirements for ultra-high agility, stability, and precision (ASP) control performance. By introducing a wide-range pointing mechanism into an ASP control architecture, the technical contradiction between wide-range agile maneuverability and ultra precision and ultra stability can be solved, but it also brings problems such as multi-stage loop coupling and modal frequency changes in the control system. Aiming at these problem, a dynamic model of an ASP control system with a wide-range pointing mechanism is established. Simulation analysis shows that the introduction of the pointing mechanism increases the low order resonance peak frequency of the payload control loop. The influence of the pointing mechanism control bandwidth on the system dynamic characteristics is analyzed. Finally, the analysis results are verified through physical experiments, providing a theoretical basis for the design of the ASP platform controller.

Key words: ultra-high agility, stability, and precision (ASP) control, pointing mechanism, multi-stage composite control, control loop coupling
