摘要
作为精密加工的核心驱动源—超磁致伸缩致动器(GMA)具有推力大、应变大、响应快等优点;然而超磁致伸缩材料的滞回特性阻碍了超磁致伸缩致动器的广泛应用。基于物理或数学方法建立的超磁致伸缩滞回模型都比较复杂,具有强非线性,很难结合到控制器的设计中。本文从控制器的设计角度与GMA的应用环境出发,建立了超磁致伸缩滞回通用模型;并采用基于线性反馈的滑模变结构控制方法设计控制器;理论及仿真结果证明并验证了此方法的有效性。
Magnetostrictive actuator（GMA） , with large strain , high force , nanometer solution , is the core driver source in the super- precision tracking system. However, magnetostrictive material exhibits dominant hysteresis, which impedes its application . Based on hysteretic Physical or Mathematical theory, the complex hysteretic model with nonlinear is very difficult to be combined with design controller. Considering the designing of controller, a general model for giant magnetostrictive materials is established, Furthermore, sliding mode variable structure con- trol based on linear -feedback is used to design the controller. The theory and simulation results validate the effec- tiveness of the proposed strategy.
