Based on the idea of redundant fault-tolerance, this paper designs a dual CPU fault-tolerant controller based on Field Programmable Gate Array(FPGA). It can detect faults and resume system performance through checkpoint reload in case of failure, and control law can self-reconfigure when sensor faults occur in the system. Simulation results show that fault-tolerance and fault rectification functions can be achieved by switching the redundant CPU and reconfignring the control law in case of system failure.
