Abstract:

This paper expounds a way of automatic multi-state fault tree construction in control systems. It puts forward the standardized description of the system and its components which are based on the function block of the control system. At the same time, it brings forward an algorithm of the process of generalized negative feedforward structure. Through these, an algorithm of the process of complicated structures in automatic fault tree construction is finally improved. Based on an example in the flight control system, this paper examines the validity of the algorithm and thus is beneficial to the real automation of fault tree construction .

Key words: system reliability, automatic multi-state fault tree construction, function block, standardized description, generalized negative feedforward
