摘要
针对深海环境下电液比例控制的特点,将2路压力传感器的检测压力输入同相并联差动放大器,利用其高共模抑制比和高输入阻抗的优点,设计了一个比较放大器,能很好地满足系统的要求。
According to the characteristics of electro-hydraulic proportional control in deep-sea,the paper put the two detection signals of pressure sensors into the parallel-connected noninverting differential amplifier,which has high CMRR and high input impedance.Then it designed a comparison amplifier,which could meet the system requirements.
