If left untreated , it is associated with oxygen desaturation , hypercapnia , and hypopnea , which can lead to significant cardiovascular problems ( e . g . , systemic and pulmonary hyper tension , cor pulmonale , and right ventricular failure ) 如不治疗，会并发血氧饱和度下降、高碳酿血症和呼吸减慢，从而导致严重的心血管疾病（如系统性和肺动脉高压、肺心病和右心室衰竭） 。

Aiming at drawbacks that environment simulate test laboratory ( estl ) ' s control precision is being dropped , the system digital simulation , the system characteristic analysis is proceeded ; basing on it , intelligence pid control processor , integral desaturation pid control processor , leading adjust control processor ( leading adjust of point of inflection of curve ) is planned , double loop control processors of low temperature system is consummated , so , the new control scheme and control program is formulated ; moreover through control program " simulate debugging and environment simulate test , 18 experimental curves and 19 experimental items is fulfilled totally . it proved that estl ' s control system and control program are successful . experimental result makes it known that the new control plan solves the problem of low control precision 本论文针对环模室原控制系统存在的控制精度下降等问题，进行了系统仿真及环境模拟系统特性分析，在此基础上，设计了智能pid控制器、抗积分饱和的控制器、预估补偿控制器、完善了低温系统的双回路控制，制定了新的控制方案和控制程序组态，并对其控制程序进行模拟调试及结合实际试验对其控制系统进行验证；共计完成了18条曲线， 19个项目的试验，对其控制系统及控制程序进行了充分的考验。
