Artificial Immune System Implementation upon Embryonic Machine for Hardware Fault - tolerant Industrial Control Applications

Living organisms demonstrate through millions of years evolution remarkably fault-tolerance, robustness and self-healing abilities. Taking inspiration from biological immune systems and embryonic processes which acquire some of these fault-tolerant properties, the paper presents the implementation of an embryonic machine with FPGA-based multi cellular architecture, which is able to imitate cells or artificial organism operation mode, with similar robustness and fault-tolerance properties like their biological equivalents from nature. This VLSI hardware structure was upgraded through specially developed algorithms, provided with strongly network communication capabilities and self-healing behaviors. Several casual faults were considered also through the test operations. Detection and localization of these hardware faults were achieved through special reconfiguration operations of active and spare artificial cells inside the embryonic array. Laboratory experiments prove high validity of the considered background theoretical approaches, the developed hardware immune system express remarkable surviving and self-healing capabilities.
