摘要
建立了球状纳卫星的基本热环境模型。提出基于PID主动热控制的温度控制策略。分别向控制对象系统中舱内仪器、辐射器以及外壳热负荷输入一定大小的阶跃变化进行MATLAB仿真试验。仿真结果显示,PID控制系统能够较为准确、快速的对纳卫星温度系统进行合理的调节与控制。
A basic thermal environment model of the spherical Nano satellite was established. The temperature control strategies was proposed based on the PID active thermal control. Certain size step signal load was inputted separately to the heat sources of the instrument, the radiator as well as the outer covering in the controlled object system, Then MATLAB simulation experiment was carried on. Results show that PID control system can adjust and control the Nano-satellite thermal system more accurately and rapidly.
