微型百叶窗能够适当解决因体积及质量限制而引起的纳卫星内部热环境高热流密度问题。微型百 叶窗驱动的智能化控制方法是亟待解决的关键技术。在球状纳卫星动态特性模型的基础上,提出了一种模 糊PI 混合控制方法。分别在舱内仪器散热增加和减少的工况下进行控制仿真。结果表明,这种并联控制系 统较之单独使用模糊控制器和传统PID控制器在控制效果和动态特性方面更佳。
The limits of nano-satellite's volume and quality may cause a high density in the cabin. Micro-blind mesh can resolve this problem properly. The intelligent control strategy of micro-blind mesh' s drive is the key technology. A dynamic characteristics model of the spherical nano-satellite was established.Based on the model,a fuzzy PI shunt-wound controller was designed. The simulation was carried on, in conditions of increasing and decreasing the equipments' heat dissipation. Results show that this new controller is superior to the fuzzy controller and PID controller in that the former works well with good control effect and high dynamic performance.
