Abstract

The IMU’s internal temperature continuously rises with the working time,resulting in changes of the inertial sensors’ zero bias and scale factors.Especially after the miniaturization design of the IMU,its internal temperature environment field becomes more complex.The outputs of IMU’s gyros and quartz accelerometers are obviously affected by temperature changes,which restrict their application in navigation systems.The IMU’s acceleration channel is mainly composed of accelerometers and analog-to-digital conversion circuit.The analog-to-digital conversion circuit’s performance level directly affects the IMU’s accuracy.This paper proposes a temperature compensation method of the acceleration channel.Firstly,establishing the temperature model between the own output of the analog-to-digital conversion circuit when there is no input current and the inertial temperature of IMU to compensate for the own output of the circuit.Secondly,compensating the outputs when the acceleration channel is connected.The effects of the temperature differences are avoided when the analog-to-digital conversion circuit is independently compensated which affects the compensation accuracy.The model of acceleration channel variation with temperature is established more precisely,and the temperature compensation accuracy of acceleration channel is improved.Taking an IMU for example,the zero temperature repeatability of acceleration channel is increased to 2-10 times and the scale factor temperature repeatability is increased to 2-3 times,the validity and reliability of the temperature compensation method are verified by experiments,thus improving the working accuracy of the miniaturized IMU in the whole working temperature range.
