Radial Basis Functions Intended to Determine the Upper Bound of Absolute Dynamic Error at the Output of Voltage-Mode Accelerometers.

In this paper, we propose using the radial basis functions () to determine the upper bound of absolute dynamic error () at the output of a voltage-mode accelerometer. Such functions can be obtained as a result of approximating the error values determined for the assumed-in-advance parameter variability associated with the mathematical model of an accelerometer. This approximation was carried out using the radial basis function neural network () procedure for a given number of the radial neurons. The Monte Carlo (MC) method was also applied to determine the related error when considering the uncertainties associated with the parameters of an accelerometer mathematical model. The upper bound of absolute dynamic error can be a quality ratio for comparing the errors produced by different types of voltage-mode accelerometers that have the same operational frequency bandwidth. Determination of the was performed by applying the Python-related scientific packages, while the calculations related both to the and the MC method were carried out using the MathCad program. Application of the represent a new approach for determining the . These functions allow for the easy and quick determination of the value of such errors.
