以某空间相机镜筒作为控制对象,建立了热分析模型,提出了基于积分分离式比例积分（PI）主动热控制的温度控制方法。积分分离式PI算法采用增量式计算、位置式输出,将输出的加热功率值转换为一个控温周期内的加热时间。以相机镜筒的热分析模型为基础,通过Ziegler-nichols参数整定方法获取积分分离式PI算法的比例参数和积分参数,利用热分析软件Thermal Desktop对空间相机镜筒进行了热分析,获取控温算法的控温性能。结果表明：积分分离式PI控制方法响应快,消除了稳态误差,较比例（P）控制具有更好的动、静态特性,适用于有高精度控温需求的主动控温设计。

Thermal analysis model of space camera＇s body tube is established. The temperature control strategy is proposed based on the integral-separated PI active thermal control. The increment can be achieved in the procedure of time running PI program and the output is the total power which will be converted into the time of heating. Based on thermal math model of space camera＇s body tube ,thermal control parameter is determined by Ziegler-nichols tuning method. Property of thermal control algorithm is obtained through thermal analysis using Thermal Desktop. Results show that integral-separated PI control can obtain quick response and eliminate the steady-state error as well. The new controller is superior to traditional P controller in that the former works with higher dynamic and static performance.
