Description
technical field [0001] The invention relates to the field of servo motor control, in particular to an intelligent control method for a fault-tolerant servo motor drive system. Background technique [0002] With the development of multi-electric, all-electric aircraft and hybrid and pure electric vehicles, the motor drive system has ushered in new development opportunities and challenges. In addition to requiring high power density and high efficiency, it also needs to have high output performance and high reliability. performance, which has become the key to the motor drive system. In the 1990s, the emergence of permanent magnet fault-tolerant motors and their control systems improved the safety and reliability of the system, and have now been applied to the aviation field. However, affected by electromagnetic interference, insulation aging, poor contact and other factors, some electrical faults often occur in the motor and power tube in the drive system, which can generall...
