基于免疫反馈算法的缝纫设备振动控制研究

摘要

The vibration is harmful to sewing performance. In order to decrease the harm, a sewing machine vibration active control system is developed, in which the giant magnetostrictive actuator is adopted, satisfying the design requirements on control precise and frequency response. The giant magnetostrictive actuator and sewing machine is modeled, on the base of the research on giant magnetostrictive actuator' s principle and sewing machine vibration character. An immune feedback controller based on artificial immune is designed, and the simulation on MATLAB with the tool of Simulink and test on the industrial sewing machine is demonstrated, the results prove that the system can effectively suppress the vibration of sewing machine from motor in sewing.%为降低缝纫设备缝纫时产生的振动对缝纫性能的影响,开发了一种缝纫设备振动主动控制系统.该系统中的执行机构采用超磁致执行器,能满足振动控制精度和频响的要求.在完成系统的总体设计后,研究了超磁致伸缩执行器工作原理以及缝纫设备机身的振动特性,并分别对他们进行建模.设计了一种基于人工免疫原理的免疫反馈控制器,采用MATLAB环境中的Simulink工具对控制系统进行建模仿真,并在工业缝纫机上进行了现场实验测试,结果证明该系统能很好地抑制缝纫时引起的机身振动.
