【摘要】 磁致伸缩材料作动器是一种具有特色的机敏材料作动器。本文在自行研制Ｔｅｒｆｅｎｏｌ－Ｄ作动器及其特性试验的基础上，研究该类作动器在主动隔振与主动吸振中的应用。文中提出并导出了多通道前馈控制的时延滤波—ｘＬＭＳ法，并就这种算法的收敛性进行进一步的讨论。更多还原

【Abstract】 Magnetostrictive actuator is a kind of smart actuators with special features. Based on self made Terfenol D actuator and the test results on its characteristics the application research on such kind of actuator as vibration isolator and absorber for active vibration control is reported in the paper. A delay filtered x LMS method for multichannel feedforward control is presented and deduced. The convergence of the algorithm is further discussed at last.更多还原
