针对永磁同步电机常规直接转矩控制系统涉及到的问题,例如磁链的准确观测、定子电阻的变化、电压矢量开关表的改进以及滞环控制器的改进等等,本文都作了详细的分析,并提出了改进方案。为了提高系统的性能,本文将空间矢量调制的方法引入了常规直接转矩控制中,并在此基础上,对永磁同步电机无速度传感器问题作了详细的分析,总结了国内外的研究热点,提出了采用转子磁链矢量为基础的永磁同步电机直接转矩控制速度估计方法。仿真结果表明,该方案具有很好的动、静态特性。(Firstly, the paper analyzes the principle of direct torque control of permanent magnet synchronous motor and elaborates the impact of space voltage vector of the stator flux and the electromagnetic torque.Secondly, the paper introduces direct torque control of permanent magnet synchronous motor SVPWM technology.Under the same hardware conditions,the system can obtain More continuous voltage space vector by taking advantage of SVPWM.The simulation results show the program not only keeps the direct torque control fast dynamic response, but also reduce the motor torque ripple.)

说明： 本文提出了一种基于混沌加密的DCT域二值图像数字水印算法.该算法首先利用混沌序列将含有版权信息的有意义二值图像水印进行加密,然后利用人眼视觉系统(HVS)的特性将原始载体图像进行块分类,最后将不同强度的水印分量嵌入到不同类的图像块DCT中频系数中去.利用混沌序列对水印进行加密,使水印本身具有安全性,对数字作品进行双重保障.通过高斯噪声,椒盐噪声以及JPEG压缩和剪切等攻击试验,表明了该算法具有较好的鲁棒性.(Encryption in DCT domain is proposed. Firstly, the meaningful binary image watermark containing copyright information is encrypted by using chaotic sequence, and then the original image is classified by using the characteristics of human visual system (HVS), Finally, the watermark components with different intensities are embedded into the DCT intermediate frequency coefficients of different types of image blocks. Chaotic sequences are used to encrypt the watermark, so that the watermark itself has security and double protection for digital works. Experiments on Gaussian noise, salt and pepper noise, JPEG compression and clipping show that the algorithm has good robustness)
