Abstract: To improve the reliability of the control system working in extreme environment, this paper combines fault-tolerance of Triple Modular Redundancy(TMR) and self-repairing of Evolvable Hardware(EHW) and realizes a FPGA (Field Programmable Gate Array) motor control system based on TMR-EHW structure. In the system, TMR is used to detect and locate fault rapidly, shut off the disabled modular and guarantee the function with fault-tolerance. The system carries through self-repairing with EHW. The disabled modular system can be recovered in this way. System reliability is improved.
