Simulation of Steady-state Fault for Whole Liquid Propellant Missile Power System

In order to analyze dynamic fault characteristic and acquire all dynamic fault patterns, the Runge-Kutta-Fehlberg(R-K-F)method is employed to solve equations of dynamic model for the whole missile power system. The dynamic fault simulating computation and characteristic analysis of transition process is performed under fault conditions, so the dynamic fault pattern base for whole power system is acquired. The calculated results show that the established model is reasonable and the numerical simulation method is effective. The study pioneers the way of fault analysis, detection and diagnosis method for dynamic process of whole liquid missile power system.
