  • Method and system for processing fault information of decoding chip in rotary transformer
    Patent number: 10972021
    Abstract: Disclosed are a method and a system for processing fault information of a decoding chip in a rotary transformer. The method includes: reading data information transmitted by the decoding chip according to a preset period; determining whether the data information includes alarm information; when the data information includes the alarm information, estimating a rotor-position value after an alarm occurs in real time according to a rotational speed in the data information obtained before the alarm occurs; determining whether a difference between a current rotor-position value and the estimated rotor-position value is greater than a fault threshold; and when the difference between the current rotor-position value and the estimated rotor-position value is greater than the fault threshold, controlling a motor using the estimated rotor-position value.
