Abstract

An interior composite magnetic material fault-tolerant tubular linear motor, and short-circuit fault-tolerant vector control method thereof. The method comprises: establishing a five-phase interior composite magnetic material fault-tolerant tubular linear motor model; using a non-failure phase current of the motor to perform compensation for a short-circuit failure phase resulting in a normal thrust deficiency in the phase, and to suppress thrust fluctuation; and obtaining, by employing a series of coordinate transformations and voltage feed forward compensation policies, a desired phase voltage, and employing a CPWM modulation method based on zero-sequence voltage harmonic injection to realize fault-tolerant vector control after a phase short-circuit failure of the motor. The method can suppress motor thrust fluctuation when the motor is in phase short-circuit fault-tolerant operation, and more importantly, the method has the advantages of dynamic state and steady state performances consistent with those in a normal state, a constant switching frequency of a voltage source inverter, and a small CPU overhead. Moreover, upon a short-circuit failure of any phase, the natural coordinate system only has to be rotated counterclockwise by a certain angle to realize fault-tolerant operation of the motor.
