| Abstract: | In order to meet above demands, redundancy technique is used in designing FLCC. Based general redundant technique design principle, authors proposed and designed a FLCC which can meets the needs of highly reliability in flight control system. It guarantees system two-fail operation, three-fail safe (fo/fo/fs). In real-time environment, managing redundancy is vital to the correct operation of fault tolerant computer. Present a approach to masking errors and achieving congruency in the presence of a fault. The FLCC's design principle, structure of hardware/software and redundant management algorithm are discussed in detail. |
