Abstract:
This paper proposes an improved PID control based on temperature compensation strategy, which can dynamically adjust the target temperature value of the PID controller according to the ambient temperature and the preset temperature compensation curve, thus basically eliminating the influence of ambient temperature on the reaction liquid temperature, and ultimately achieving stable reaction liquid at the preset temperature under different ambient temperature conditions. Through experiments, it was found that after adding temperature compensation strategy to the PID control, the maximum steady-state temperature difference of the reaction liquid decreased from 0.31℃ to 0.11℃, and the coefficient of variation (CV) of Relative Light Units (RLU) decreased from 4.22% to 1.43%.
