摘　　要：在分析了航天器热控制需求以及电子控温装置应用现状的基础上,对分布式控温技术进行了初步研究,提出了用于分布式控温的精密恒温固态控制器技术方案。方案设计兼顾了控温精度和设备安装灵活性的需求,采用脉宽调制(PWM)控制作为控制方式,研制的工程样机控温精度优于0.1℃,尺寸为20mm×25mm×30mm。该装置适用于有高精度控温需求,且要求控温装置占用航天器资源较少的主动控温设计。Distributed temperature control technic was studied preparatorily. Technical design of Solid - State Controller for precise temperature control was introduced. This design was on the basis of China aerospace thermal control requirements and the reality of electric temperature control device application. Temperature control precision and device installation flexibleness were both considered in this design. Pulse - width modulation （PWM） control method can make temperature control precision be less than 0.1℃. Engineering product with the dimension of 20 mm ×25 mm × 30 mm was manufactured. It can be used in precise temperature control with little aerospace resource occupied.
