Due to the large torque coefficient, small torque ripple and ease of control, permanent magnet synchronous motor (PMSM) system has been widely used in many accurate servo control systems.
Search efficiency is improved by embedding synchronous signals into time domain. Better robustness is achieved by hiding the watermarking into the low frequency coefficient of DWT domain.
同步信号嵌入时域，以提高搜索效率，水印隐藏在离散小波变换域的低频系数中，以达到较好的鲁棒性。
