摘　　要：在开发传统的sEMG识别控制系统时,一般采用软件算法研究与硬件实现相分离的方法,容易造成识别控制算法的"理想化"。设计一种基于虚拟仪器的sEMG识别控制系统,该系统平台基于LabVIEW及数据采集设备、MATLABScrip节点程序和机械臂执行机构,实现了对sEMG识别控制系统的半实物仿真控制,使算法研究与硬件实现相结合,缩短了真实系统的开发时间,提高了控制算法的准确性和实用性。Traditional method of sEMG recognition and control system development is always ＂software simulation first, hardware implementation second＂, which always leads to the idealization of arithmetic and the separation between simulation and implementation. A platform for sEMG recognition and control was designed based on virtual instrument. Data collecting equipment, Matlab Scrip program and mechanical arm executing agency were used to realize the semi-practical simulation control and simulation algorithm was combined with implementation. The development time of the control actuator is shortened and the accuracy of the control algorithm is improved.
