光学头是高密度光盘系统(DVD)一个关键部件,PID控制是一种经典的DVD光学头控制方式,PID参数是否合理直接影响光学头控制性能,为了提高DVD的光学头控制精度,提出一种蚁群PID的DVD光学头控制算法。采用PID控制器对DVD光学头进行控制,并通过蚁群算法对PID控制参数进行在线性调整和优化,采用VC++对控制性能进行测试。结果证明,本文方法获得良好的DVD光学头的控制效果,具有较好的鲁棒性。
The optical head is a key component of high density optical disk system (DVD). PID control is a classic DVD optical head control method. Whether the PID parameters are reasonable or not directly affects the optical head control performance. In order to improve the optical head control accuracy of DVD, Ant Colony PID DVD Optical Head Control Algorithm. The PID controller is used to control the DVD optical head, and the PID control parameters are adjusted and optimized linearly by the ant colony algorithm. The control performance is tested by VC ++. The results show that the method of this paper get a good control effect of the DVD optical head, with good robustness.
