Some problems of inertial measurement units modeling in matlab and matlab/simulink

Abstract

Paper presents work based on the comparative analysis of output signals errors of primary measuring instruments of the inertial measuring module, such as – accelerometers and gyroscopes. With use of the identified parameters of metrological model of the inertial measuring module, and mathematical program providing Matlab/Simulink. By results of modeling it is carried out the analysis of output signals errors of the measuring IMU converters, on the basis of two types of modeling in the Matlab environment: with application of listing and M-file, and with creation of Simulink model with use of auxiliary blocks “From-file” and “Subsystem”.
