摘　　要：传统热控技术在空间探测任务确定后,基于特定输入条件设计的控制方案,其自适应能力不足,且存在一定的时滞性。文章从系统工程学的角度,提出了基于空间热环境预判的航天器智能自主热控方法,采用航天器姿态规划实时预测外热流,开展相应的控制措施,实现对温度的前馈控制,并进行了仿真验证,结果表明:该方法可有效弥补传统热控技术在空间探测任务中调温能力的不足。在航天器高精度控温和大功率散热领域,能有效抑制低频噪声,节约热补偿功率,具有广泛的应用前景。Traditional thermal control technology depends on the specific design input of the space exploration mission,which makes it not self-adapting enough and there are certain time lags.A spacecraft intelligent autonomous thermal control method based on space thermal environment prediction is proposed in this article from the perspective of systems engineering,which uses spacecraft attitude planning to predict the external heat flow in real time,and implements corresponding control measures to achieve feedforward control of temperature.Simulation verification is carried out,and the results show that this method can effectively make up the temperature adjustment ability shortage of traditional thermal control technology in space exploration tasks.In the field of high-precision temperature control and high-power heat dissipation of spacecraft,it can effectively suppress low-frequency noise and save thermal compensation power,which makes a wide range of application prospects.
