摘要

针对单自由度磁悬浮系统，提出了一种结合模糊增益调度的精确前馈线性化控制器。该方法在瞬态响应特性和跟踪误差方面改进了先前报道的技术。实现了非线性/不确定对象的Luenberger状态估计器。最后，将控制律与估计器相结合，并在磁悬浮系统中进行了实验应用。结果表明，该方案在跟踪信号动态范围增大和载荷变化情况下具有较好的鲁棒性和有效性。

Fuzzy logic-based gain scheduling of Exact Feedforward Linearization controller for magnetic ball levitation system

This paper presents an Exact FeedForward Linearization controller combined with fuzzy-based gain scheduling for single DOF magnetic ball levitation system. The proposed method improves the previously reported techniques in terms of transient response behavior and tracking error. A Luenberger State estimator for the nonlinear/uncertain plant is implemented. Finally, the control law and the estimator are combined and applied experimentally to the magnetic ball levitation system. The results show the effectiveness and the robustness of this scheme regarding the increase of the dynamic range of the tracked signals and the presence of payload variation.
