%X 为解决复杂电磁环境中冗余容错电路系统容错形式单一、容错能力有限、冗余单元利用不充分和可靠性低等问题,提出了一种新颖的交互式？残？同故障容错(ICFT)技术。根据整个电路系统预期输出信号,利用硬件本身冗余无故障单元替换故障单元。结合硬件演化(EHW)和补偿平衡技术(RBT),当冗余无故障单元不足时,采用被动式ICFT技术对既有故障实现容错。当采用被动式ICFT技术失败时,采用主动式ICFT技术,通过注入故障并重新分配子电路功能实现容错。仿真结果表明:与常规冗余容错(CRFT)和硬件演化(EHW)相结合的技术CRFT？？EHW相比,采用ICFT技术能够容忍的工作电路最大故障单元累积量为41个,远大于采用CRFT？？EHW技术时的16个。<br>A novel design technology for fault tolerance circuit systems based on interactive？？collaborative fault tolerance (ICFT) technology is proposed to solve the problems that the redundant fault tolerance circuit systems have single fault tolerance form, their fault tolerance ability is limited, the use of redundant units is insufficient, and the reliability is low in complex electromagnetic environment. Fault units are replaced by redundant trouble？？free units according to the expected output signals of the whole circuit system. When there are not enough redundant trouble？？free units, the evolvable hardware (EHW) and the reparation balance technology (RBT) are combined, and then the passive？？ICFT technology is used to achieve fault tolerance for existing fault. The active？？ICFT is used only when the passive？？ICFT fails, and then sub？？circuit functions are redistributed. Simulation results show that the max faults units cumulative of working circuit of ICFT technology are forty？？one, which are far greater than sixteen of conventional redundant fault tolerance and EHW (CRFT？？EHW) technology
