The EMG Control System's Designing of Prosthetic Hand Based on DSP

介绍了一种基于DSP的肌电信号采集、分析系统。根据肌电信号的特点,以DSP嵌入式系统为控制核心,采用AgCl电极作为肌电信号传感器,可以实现6通道肌电信号的采集。该系统通过信号放大、滤波电路的设计,结合信号处理算法的开发实现,完成了6个电机控制信号的输出,最终实现了欠驱动肌电控制假肢。仿真结果表明,该系统的动作识别准确率可达96.66%。

We research on an acquisition and analysis system based on DSP for EMG in this paper.According to the characteristics of EMG,the system is adopted DSP as the core of control and used AgCl electrode as EMG sensors.The system can collect 6-channel EMG signal.The system can input six motors control signal by mplification signal,filtering circuit,and signal processing＇s algorithm.Ultimately,the system can achieve the underactuated control for artificial limb.The simulation results show that the system＇s recognition action accuracy rate is 96.66%.
