摘要
针对超磁致伸缩驱动器的动态输出特性的响应问题 ,从驱动器的驱动电源和控制算法两方面入手 ,提出了改进方法 ,并形成了一个完整的计算机测控系统。试验表明 ,该系统简单、可靠、实用 。
The problem of slow step response in giant magnetostrictive actuator was studied and both driving power of the actuator and a digital PID method were adopted to compensate the slow step response,while a whole computer measurement and controlled system was formed.The experiment shows that the control system is a simple,reliable,and practical one,the dynamic output characteristics of giant magnetostrictive actuator based on the driving power and the digital PID method is very ideal.
