摘要：
According to the individual design and online monitoring of the local environment control system, and combined with a sealed air cooling constant temperature control apparatus, a constant temperature control strategy similar with fuzzy control has been proposed. The experimental results show that the steady-state temperature fluctuation is in the range of 0.2 degrees C, and with good robustness. The ICA (Independent Component Analysis) method was adopted to separate and monitor the working state of the internal precision instrument, and the test results were in good agreement with the experiments. In addition, the monitor of system structure state changes using the observed temperature has been discussed and a new option to improve the online monitoring capacity of the internal precision measuring instrument has been provided for the local environment control system.
