摘要（英）：

The invention discloses a method for parameter identification of a switch reluctance motor. The method comprises: step A, a current signal containing a direct-current component and an alternating-current component is applied to a switch reluctance motor; step B, the working state of the switch reluctance motor is controlled, so that the switch reluctance motor is in a single-phase test state; stepC, a voltage sensor and a current sensor collect voltage and current signals of a three-phase winding of the switch reluctance motor; step D, the collected voltage and current signals are inputted into a neural network for modeling; step E, FFE operation is carried out on voltage and current data; and step F, according to a motor equivalent model, various operation parameters of the switch reluctance motor are calculated. Therefore, the operation parameters of the switch reluctance motor can be identified quickly with high identification precision.
