温控系统区域间温度场耦合补偿方法研究
摘要
基于半导体制冷器的常规恒温控制系统中
每块半导体制冷器仅基于所控制区域温度信号对该区域进行调整

提高被控系统的温度稳定性。
Abstract
In conventional constant temperature control system based on TEC
every TEC adjust controlled region only based on the region temperature signal
interregional temperature field coupling will lead to stability variation of the control system.Aiming at this problem
a solution of interregional temperature field coupling compensation is proposed.Divide the controlled circuit system into several control regions
and establish model of interregional temperature field coupling according to system structure
quantify coupling effect
then compensate current region control algorithm.Simulation results show that this method can effectively suppress influence of interregional temperature field coupling
and increase temperature stability of the controlled system.
