磁悬浮系统的稳定性是通过使用带有非线性积分器的低通滤波器（LPF）来实现的，无需任何其他元件。比例微分 (PD) 控制通常用作稳定磁悬浮系统的最简单方法。同时，采用一阶复位元件（FORE）来改善瞬态特性。最初的 FORE 是带有非线性复位积分器元件的一阶 LPF。磁悬浮系统无法通过线性 LPF 或原始 FORE 来稳定。在这项工作中，FORE 的复位条件针对磁悬浮进行了修改。这种改进的 FORE 成功地稳定了磁悬浮系统。改进后的 FORE 的有效性通过模拟和实验得到了证明。实验中采用单自由度磁悬浮系统。
The stabilization of a magnetic suspension system is achieved by using a low-pass filter (LPF) with a nonlinear integrator without any other element. A proportional-derivative (PD) control is commonly used as the simplest method of stabilizing a magnetic suspension system. Meanwhile, a first-order reset element (FORE) was applied to improve transient characteristics. The original FORE was a first-order LPF with a nonlinear reset integrator element. A magnetic suspension system cannot be stabilized by a linear LPF, nor the original FORE. In this work, the reset conditions of the FORE were modified for magnetic suspension. This modified FORE succeeded in stabilizing a magnetic suspension system. The efficacy of the modified FORE was demonstrated by simulations and experiments. A single degree of freedom magnetic suspension system was used in the experiment.
