Example Embodiment
[0034] Embodiment 1. A method for estimating the stator flux linkage of a motor, the steps of which are: compensating the calculated phase and amplitude of the stator back electromotive force, and converting the compensated stator back electromotive force into a stator flux linkage through a low-pass filter , Wherein: it also includes the step of determining the cut-off frequency of the low-pass filter, specifically the stator flux linkage angular frequency is calculated through the stator flux linkage, and then the cut-off frequency of the low-pass filter is determined according to the stator flux linkage angular frequency.
Example Embodiment
[0035] Embodiment 2. A method for estimating stator flux linkage of a motor, wherein: the step of determining the cut-off frequency of the low-pass filter according to the angular frequency of the stator flux linkage is: when the angular frequency of the stator flux linkage is less than When the low-pass filter cut-off frequency is set at the lower limit value A; when the stator flux angular frequency is at with Between, the cut-off frequency of the low-pass filter is proportional to the angular frequency of the stator flux linkage, that is ; When the stator flux angular frequency is greater than When, the cut-off frequency of the low-pass filter is set at the upper limit amplitude B, and the rest is the same as in embodiment 1.
Example Embodiment
[0036] Embodiment 3. A method for estimating the stator flux linkage of a motor, wherein: the lower limit value A means that the cut-off frequency of the low-pass filter is maintained at a preset minimum allowable value, and the rest is the same as in embodiment 2.
