Abstract

At high and low speeds, the back potential is not the same, but the flux linkage of the rotor is basically similar. If the flux link is used as the observation object, the negative effects of SNR and nonlinear factors at low speed can be avoided. Based on the principle of flux model, this paper builds a flux observer model. The test results show that it can run stably at low speed, has strong load capacity, smooth switching at low speed and high speed, and fast convergence at high speed.
