强干扰条件下超磁致伸缩致动器的模糊滑模动态控制
Fuzzy Sliding Mode Control of Giant Magneto-restrictive Actuator under Strong Perturbation

针对强干扰条件下，超磁致伸缩致动器位移动态控制存在的不足，建立了强干扰下超磁致伸缩致动器动态线性化模型，设计了基于模糊切换增益调节的滑模控制器，实现了致动器的动态跟踪控制。提出的模糊滑模控制器能有效实现了致动器的动态控制，位移跟踪误差在5%以内，取得了良好的控制效果。
To exercise the dynamic positioning control of Giant Magneto-restrictive Actuator (GMA) for high precision, it is very crucial to compensate for the impact of strong perturbation derived from structurally inherent uncertainties and outside circumstances. In this paper, a model that considers the perturbation of GMA is established. A sliding mode controller with self-tuning shift gains based on fuzzy control is designed to realize the position tracking of GMA for high precision. The effectiveness of the GMA is verified, its tracking error being below 5%
