摘要
针对数字方法实现重复控制存在的成本高,信噪比低等问题,对使用MN3004实现重复控制器中的时延环节进行了实验验证,并对其消除周期性扰动的性能进行了仿真分析.实验证明MN3004可实现高精度的时间延迟,仿真结果表明用这种方法实现的重复控制可以很好地消除周期性干扰,实现对周期性信号的高精度跟踪.
Aimed at the shortcomings of high cost and low SNR occurred in realizing digitally the repetitive control, the delay link in the repetitive controller implemented by using MN3004 was verified with experiment, and the performance of eliminating periodic disturbance was simulated and analyzed. It was proved that the delay with high accuracy can be achieved by using MN3004, and the simulation results show that the periodic disturbance can be eliminated well, and the high accurate tracking of the periodic signals can be realized by the presented method of repetitive control.
