Abstract


To improve the precision of strapdown inertial measurement unit(SIMU)in all-temperature range, this paper focuses on the research of temperature control technique and temperature compensation method for key part of the strapdown inertial measurement unit(SIMU).The main contribution of this paper consists of the following aspects:(1)As for IMU that has enough available time, we adopt temperature control method for senstive assemblies and inertial apparatus to improve the precision of IMU.(2) As for IMU that has not enough available time, we develop fast temperature error compensation method to compensate it in real time.(3) As for as the factor that affects the temperature of fiber optic inertial measurement unit and inertial sense organ, we build mathematic model analysis and draw conclusion in detail.(4) As for as IMU that adopted temperature control method, the experiment results demonstrate the validation of model and analysis by designing temperature control circuit.(5) As for IMU that adopted temperature compensation method, the experiment results demonstrate the expected results that are realized based on the temperature compensation model of inertial apparatus.As far as temperature control technique is concerned, we analyse the reason that every tache is affected by temperature and affected degree from principle basing on the composition of typical SIMU, environment temperature, and temperature property of sense organ. As for the technique indices of a product specification, we developed a digital temperature control method and algorithm based on hierarchical and time-sharing control strategy, and designed the hardware and software of temperature control system. Finally, practical test results demonstrated the expected technique indices are realized based on temperature control technique.Meanwhile,as far as temperature compensation technique, this paper takes laser peg-top inertial measure unit for example, analyse quartz flexibility accelerometer and temperature error compensation model, develop temperature compensation method combined curve fitting after temperature scanning and fixed point temperature correction. Experiment result demonstrates the effectiveness of the proposed method.
