Motor Control System with High Reliability Based on TMR-EHW
WU Cai-hua · Jisuanji gongcheng · 2009
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.
