  1. To accept the current signal from high negative voltage circuit, the analog ground is raised to a certain positive voltage, which makes it possible for the signal amplitude to be compressed at the same time of its polarity reversion. a pi control program special for laser gyro current control is brought forward according to the conventional pid control method, in which the control signal is figured out corresponding to the difference between the sample and the reference value by turn of proportion - short step integral - long step integral. and at the end of this paper, a comparison of system performance on different conditions is made and the key elements influencing system performance are educed
