title = "Micro-displacement positioning of giant magnetostrictive actuator",
abstract = "Giant magnetostrictive materials have a broad potential application in aviation and aerospace field owing to its good properties. The actuators made of the materials show excellent performance which makes them a good choice for precision positioning. This paper presents a micro-displacement positioning system of the giant magnetostrictive actuator (GMA). The structure of the system and its control method are described. In order to achieve the steady micro-positioning characteristics, the adjustment process of the system based on the control algorithm of Programmable Multi-axis Controller (PMAC) was researched. The response time of the GMA was less than 1 ms which was shown in the step response curve. Relatively large displacement (5\textasciitilde{}20 μm) positioning and micro-displacement (0.9\textasciitilde{}3 μm) positioning were achieved with the average positioning systematical errors of less than 0.5 μm.",
