电子式氧气调节器中步进电机模糊控制技术研究

摘要

According to the working principle and the control law of the aircraft electronic oxygen regulator (AEOR), stepping motor control is the focus and key of AEOR design. By analyzing the influences of two methods that the distance of sub-step adjusting motor with constant speed or variable speed on the capability of the AEOR, the fuzzy control method and the design process are introduced in detail. Through pilot testing AEOR in the field, the method is proved to be effective and satisfying for achieving the purpose of human breathing comfortably.%通过介绍电子式氧气调节器的基本原理和控制规律,分析了步进电机的控制方法在电子式氧气调节器设计中的意义和作用.针对恒速分段调节步进步距和变速分段调节步进步距两种步进电机控制方法存在的问题,介绍了模糊控制的方法,并详细分析了设计实现的过程.试验结果表明,采用模糊控制电子式氧气调节器步进电机的方法实现了人体舒适呼吸的目的,也解决了步进电机丢步以及频繁动作带来的工程问题,提高了产品的可靠性.
