超磁致仲缩材料在心血管支架加工中微进给补偿控制中的研究

基于超磁致伸缩材料特性对微位移进给进行研究，设计了磁致伸缩致动器应用于心血管支架的加工，建立了致动器的传递函数模型。同时针对超磁致伸缩材料受温度，预紧力等因素影响对位移输出产生较大偏差，设计了PID调节器，并对磁致伸缩致动器控制系统给出了基于MATLAB的仿真，并在此基础上进行了离散化，得到了数字控制系统，并应用到实际中，并对实际输出位移进行对比。经过PID闭环控制调剂后，位移输出有了明显的稳定。

Standing for Micromovement compensate control with GMM in cardiovascular stcnt machining

In this paper, according to GMM for research to design the magnetostrictive actuator for machining cardiovascular stent, and then Setting up the actuator transfer function model. Becausee of the GMM is effected by the temperature and preloaded force, then adding the P1D regulator for the control system to compensate the displacement deviation, and rendering based on MATLAB policy eurve.h has get the digital control system from the discretization, then testing actual output displacement, it is better than before.
