音圈电机在电子式供氧抗荷调节器中应用研究

摘要

Traditional oxygen regulators are mechanical,which has disadvantages of large volume,slow response and low accuracy adjustment.A new type aircraft electronic oxygen regulator(AEOR) is developed,by analyzing system composition and working principle,a segmented stepping algorithm is designed based on the voice coil motor.According to the size,plus and slope of pressure difference,voice coil motor is controlled,and the size of respiratory cavity is adjusted,which makes breath balance.The algorithm is also used in the resistance test.The experiment results indicate that the segmented stepping control algorithm can accurately control the voice coil motor and meets the technical specifications on the respiratory resistance index,which has higher adjustment accuracy and faster response,the AEOR reaches the design requirements of the new generation of fighter aircraft oxygen supply sub-system.%传统的氧气调节器均为机械式,其体积较大,响应速度慢,调节精度低.针对某新型机自主研制出一套电子式供氧抗荷调节器装置,介绍了其系统组成和工作原理,并针对音圈电机的工作原理设计出一套分段步进算法,根据呼吸腔与目标腔压差大小、正负及斜率等控制音圈电机动作,进而调节呼吸腔压力大小,使吸入氧气与灌入氧气平衡,并将此算法应用于抗荷测试试验.结果表明,采用分段步进的控制算法可以对音圈电机进行精确控制,在呼吸气阻力方面满足技术指标,调节精度高,响应速度快,达到了新一代战斗机供氧子系统的设计要求.
