Abstract

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.
