摘要
本文针对海军舰艇装备中发射管装置内特殊环境下的恒温控制系统，进行了总体结构设计、控制对象的建模、PID实现。根据高可靠性、实用性强、操作方便的设计原则，合理设计了温控系统的总体结构；针对加热系统的复杂性，为使被控对象的温度均匀分布，依据传热理论对系统被控对象模型进行了设计；在系统的硬件设计中，通过采用铂电阻温度测量电路，提高测量的精度和灵敏度，通过采用16位的A/D变换器可以大大减小采样误差，通过提高系统的采样频率改善系统控制的灵敏度，通过提高系统软件的运算精度进而提高系统输出功率占空比的调整精度。

Abstract
The paper aims at in the navy warship equipment , the constant temperature control system of transmitting tube under the special circumstances to carry on the whole strctural design , the model of controlled target , and the achievement of PID . According to the design priniciple of high reliability strong practice、convenient operation , design rationally the whole structure of controlled temperature system ; To the complexity of heating system , in order to make the temperature of controlled object be well distributed . Making the design of model of system controlled object according to the theory of transmitting heat ; In the hardware design of system , measurring the circuit through chosing the temperature of platinum reistance to improve the AID transform machine that can let up the sampling error consumedly , through improving the sampling frequency of system to improve the sensibility of system control , though improving operation accuracy of the system software to improve the adjustment accuracy of the system output rate work duty ratio .
