舰船低温环境模拟室温度控制调节系统动态特性分析研究

A Study of Dynamic Charateristic of Temperature Control System for analogy Test Chamber of Ship's Low Temperature Environment

在工程允许的假定条件下,本文推导了冷气机转速与室体温度之间的微分方程式关系,再通过拉氏变换,进一步推导出温度调节系统的传递函数,以建立起控制信号与温度之间的量值关系,从而达到以变动冷气机转速来控制模拟室温度的目的。

In this paper, a differential equation of the relationship between rotation speed of the refrigerator and temperature inside the analogue chamber under asuumed engineering conditions is established, and a transfer function of the temperature control system through Laplace's transformation is further derived, so as to establish quantitative relationship between control signal and the temperature inside the chamber.
