代码说明:

说明:  我们描述了所提出的方法对超声(US)信号的压缩多路复用的直接应用。该技术利用压缩多路复用器架构进行信号压缩,并依靠频域中US信号的联合稀疏性进行信号重建。由于换能器元件具有压电特性,因此可以获得有关US信号频率支持的准确先验知识,并且可以在联合稀疏算法中使用。 我们在数值实验中验证了所提出的方法,并显示了它们在秩次缺陷情况下相对于最新方法的优越性。我们还证明,与没有已知支持的重建相比,该技术可显着提高体内颈动脉图像的图像质量。(We describe a direct application of the proposed methods for compressive multiplexing of ultrasound (US) signals. The technique exploits the compressive multiplexer architecture for signal compression and relies on joint-sparsity of US signals in the frequency domain for signal reconstruction. Due to piezo-electric properties of transducer elements, accurate prior knowledge of the frequency support of US signals is available and can be used in joint-sparse algorithms. We validate the proposed methods on numerical experiments and show their superiority against state-of-the-art approaches in rank-defective cases. We also demonstrate that the techniques lead to a significant increase of the image quality on in vivo carotid images compared to reconstruction without known support.)

  • EMG_LP_Kalman_filter
    说明:  表面肌电信号是肌肉收缩时伴随的电信号,是在体表无创检测肌肉活动的重要方法。由于设备采集到的肌电信号会受到环境噪声等影响,因此在进一步分析之前需要对采集的肌电信号进行去噪处理。 设计一种传统滤波器(如Buttterworth)和现代滤波器(Kalman)对所采集的肌电信号进行处理,并比较各个肌肉的做功比。(Surface emg signal is the concomitant signal of muscle contraction and is an important noninvasive method to detect muscle activity on the body surface. Because the electromyographic signals collected by the equipment will be affected by environmental noise, it is necessary to de-noise the collected electromyographic signals before further analysis. A traditional filter (such as Buttterworth) and a modern filter (Kalman) are designed to process the collected emg signals and compare the work ratio of each muscle.)

  • 基于模糊PI控制的BLDCM直接转矩控制
    说明:  针对双闭环矢量控制的三相电压型 PW M 整流器难以用准确的数学模型描述、以及通过其简化的数学模型求得的PI参数需要实验整定的问题 ,提出了基于模糊 P I控制器的新型智能化控制方法。与传统的Pl控制方法相比。该方法不仅实现了PI参数的自整定。还使系统具有更好的响应性能、更高的稳定性及鲁棒性。利用 M atlab/Sim ulink 工具箱建立了基于模糊 P l控制器的整流器仿真模型,并通过仿真实例对此设计方法进行了实验验证。(In order to solve the problem that it is difficult to describe the three-phase voltage type PWM rectifier with double closed-loop vector control by accurate mathematical model and the PI parameters obtained by its simplified mathematical model need to be adjusted by experiment, a new intelligent control method based on Fuzzy PI controller is proposed. Compared with the traditional PL control method. This method not only realizes the self-tuning of PI parameters. It also makes the system have better response performance, higher stability and robustness. Using Matlab / Simulink toolbox, the rectifier simulation model based on Fuzzy PL controller is established, and the design method is verified by simulation example.)
