The main accelerometer parameters and characteristics, MEMS accelerometer errors and their causes are considered. The main error types, their features and causes of occurrence are listed. Using the basic accelerometer parameters for a range of ±1g, a MEMS accelerometer was simulated in the MATLAB Simulink software package without considering measurement errors. This model of the MEMS accelerometer has been modified to take into account the temperature measurement errors and the input signal noise components, including flicker noise, to assess the real operation of the MEMS accelerometer. According to the obtained simulation results, conclusions were made about the effect of various errors on the actual operation of MEMS accelerometers in simulation.
