Description
technical field [0001] The invention relates to the technical field of synchronous motors, in particular to an intelligent fault-tolerant device for synchronous motor positions. Background technique [0002] At present, with the development of servo motors, in the fields of aviation airborne equipment and fuel systems, the requirements for intelligence and automation are getting higher and higher, so the requirements for motor control accuracy are getting higher and higher, thereby increasing the position acquisition accuracy. Requirements, in addition to hardware support, software is required for position fault-tolerant processing, so as to perform real-time high-precision control of the motor. [0003] Conventional motor controllers are susceptible to external interference for position acquisition, which affects the control accuracy of the motor, thereby affecting the flight tasks of aviation airborne equipment and the control tasks of fuel pumps. To this end, it is neces...
