摘　　要：介绍了一种基于TMS320F240数字信号处理器(DSP)的星载斯特林制冷机温度控制系统的软件设计。主要研究了系统的制冷软件控制实现策略。为提高制冷系统反馈温度实时性,对软件进行了优化设计。实验结果表明,系统中断响应性能良好,能够快速高效地实现制冷控制和温度反馈。The software design of spaceborne refrigeration control system based on DSP TMS320F240 is intro- duced. Implementation strategy on refrigeration control software is studied. In order to improve temperature- feedback real-time quality of refrigeration system, the software design is optimized. Pratical testing shows that the system has a good performance of interrupt response, which can accomplish refrigeration control and tem- perature feedback quickly and efficiently.
