The invention discloses a controller system applied to a motor, the system is provided with a processor used for processing a fault and controlling an algorithm and a CPLD/FPGA used for identifying the fault, the CPLD/FPGA is connected with the processor through a transmission bus and transmits a position signal to the processor, the CPLD/FPGA is connected with the processor through a hard wire and receives a Task signal sent by the processor; and the CPLD/FPGA identifies whether a processor Task signal has a crash phenomenon or not, and if so, the CPLD/FPGA performs fault wave closing processing on the processor. According to the controller system, the hardware rapid processing characteristic of the CPLD is utilized, faults can be rapidly recognized and processed, the CPLD and the processor can mutually detect the dead halt state of each other, and the CPLD can detect each processing task of the processor; in addition, the CPLD can rapidly obtain position signals of the motor in real time, a rotary transform
