| description | In order to eliminate the angle error caused by amplitude imbalance and phase non-orthogonality of resolver sine and cosine feedback signals, dq transform and positive and negative sequence separation are carried out to resolve sine and cosine feedback signals, and a software decoding algorithm based on positive and negative sequence separation is proposed. The decoding algorithm extracts the negative sequence component from abnormal signals, and uses the negative sequence component to compensate the decoding angle. The decoding algorithm can effectively eliminate the angle error of double frequency and DC component error caused by negative sequence component. Finally, the algorithm is simulated and verified by experiments. Experimental data verify the effectiveness of the proposed algorithm. |
