摘要
灰色预测是一种对灰色系统进行白化的算法,该算法需要的信息少、通用性强、计算量小。在磁盘驱动器控制系统中,采用灰色预测算法可以克服常规PID控制存在的滞后和超调的缺点。以灰色系统理论为基础,构造了灰色PID控制算法,对系统不确定部分建立灰色模型,进行灰色预测补偿。经仿真实验表明,该算法可以提高控制质量,获得较好的控制跟踪效果。
The grey prediction is a kind of whitening algorithm,it needs less information and caluclation. In the disk driver control system,the grey prediction can overcome some disadvantages in PID. Based on the grey system theory,a grey PID control algorithm is constructed. We set up grey models for uncertain part of system and do grey prediction compensation. Through simulation,it is shown that the algorithm can improve control quality and achieve better control track effect.
