提出了一种基于支持向量机的自适应前馈控制的初值设计方法。采用自适应前馈控制来补偿定位控制系统中由扰动引起的位置误差。虽然在以往的研究中已经验证了自适应控制的有效性，但实验结果表明，自适应控制主要存在两个问题。自适应算法需要时间来收敛自适应参数，并且在实验中性能可能会有所不同。为了克服这些问题，我们提出了一种通过设定初始值来改善自适应前馈控制收敛性的方法。在硬盘驱动器上的实验结果表明，该方法可以改善收敛时间和性能变化。
This paper presents design method of initial value in adaptive feed-forward control by using support vector machine. The adaptive feed-forward control are implemented to compensate for disturbances induced position error signals in positioning control systems. Although the effectiveness was verified in previous studies, experimental results show that the adaptive control have mainly two problems. The adaptive algorithm requires time to converge the adaptive parameters and the performance may vary in experiments. To overcome the problems, we have developed an improvement method of convergence for adaptive feed-forward control by setting initial values. The experimental results in hard disk drives show that the proposed method can improve the convergence time and the performance variation.
