Accelerometer Static Calibration based on the PSO algorithm

摘要：

　　This paper introduces MEMS accelerometer static calibration method based on the PSO algorithm.According to the mathematical model of the MEMS accelerometer,the PSO algorithm is applied to estimate the mathematical model,including scale factors,bias,and installation errors.The method does not require a three-axis rotary platform,and the calculation is simple,easy to implement,high accuracy and provides a new choice for outdoor testing environment.Analyzing the experimental data,the random errors in the sampling process have been eliminated effectively,and the calibration effect is better than the commonly static correction method.
