Abstract

Covariance Analysis Describing Function Technique (CADET) is considered too crude for precision analysis of systems with parametric perturbation. We present new precision analysis method for missile attitude control system with parametric perturbation considered. Based on the traditional CADET method, the generalized nonlinear part including parametric perturbation is statistically linearized. The differential equations of state mean and covariance are obtained. We simulate a missile attitude control system, using respectively modified CADET method and Monte Carlo method. The results and their analysis show preliminarily that modified CADET method can indeed analyze the precision of missile attitude control system with both disturbance and parametric perturbation.
