The Application of T-S Fuzzy Fault Tree Analysis in Satellite Attitude Control System

摘要：

In this paper, T-S fuzzy fault tree is applied to analyze the reliability of satellite attitude control system. T-S fuzzy fault tree analysis is discussed, and the basic events are described by Gaussian-Trapezoid membership functions. Then a T-S fuzzy fault tree is established for a satellite attitude control system. Based on known failure rates of the basic events, the system failure rate is calculated and predicted. From the calculation of fault states, fault propagation mechanism is qualitatively analyzed and an importance evaluation method is proposed. Finally, online importance evaluation for the sensor failure subtree of satellite attitude control system is performed, with providing references for condition maintenance.
