This paper mainly analyses the demands on Electrical Load Management Center (ELMC) in advanced aircraft s Fault Tolerant Electrical Power System (FTEPS), studies its structure, develops it with a top-down design, and introduces the features of the developed ones at last.

Because of its unique structure and outstanding characteristics, fault-tolerance power supply system based on dual-winding doubly salient electro-magetic motor is one ideal kind.

In order to solve this problem,a new method for designing BIT fault diagnosis strategy for fault-tolerant systems,considering reliability and testing costs,was proposed based on dynamic fault tree model.

A fault-tolerant system experiences a crash due to hardware components faults or progressive performance degradation as an"aging"phenomenon,because of running continuously for very long periods.

By the example of applying it on the(N+M) fault-tolerant system,analyzes its performance,results show the search efficiency and accuracy of improved particle swarm optimization algorithm are better than general.

In this paper (N+M) fault tolerant systems are studied theoretically.

The basic principle about dynamically re configurable FPGA was introduced and an new design method about the fault tolerant system of digital circuits was presented.

N+M) fault tolerant system (FTS) makes full use of the hardware and software of its own, and intelligent networking is a practical way to implement it, so that it is expected to have wide application in control systems.

But it can not be use d to analyze the reliability of fault tolerant systems.
