Application of Cumulant Coefficients for Solving the Problems of Testing and Diagnostics in Control Systems

Abstract

The analysis of using the estimators of cumulant coefficients of noise diagnostic signals as a statistical criterion for solving the problems of testing and diagnostics of technical objects is conducted. The sample sizes needed to distinguish the states of an object with a priory defined type I error are determined for the diagnostic signals with typical symmetrical non-Gaussian distributions of their instant values.
