| 摘 要： | 为了改善工业过程稳态控制的动态品质,对在重复性控制较为实用的PD型迭代学习控制算法进行改进,引入积分环节,以适应工业过程稳态控制;针对带有噪声的系统输出信号进行滤波,改进局部对称双积分型迭代学习控制算法,提出了基于递归最小二乘法(Recursive Least Squares,RLS)滤波的PID型迭代学习控制算法,以期过滤噪声的高频和低频分量,获得更为理想的系统输出.最后给出了相关的仿真试验结果.

| Abstract: | In order to improve procedure of industrial process steady-state optimization,integral unit was added to PD-type iterative learning controller,which is practical in repeatable control system.Furthermore,an improved PID-type iterative learning control based on RLS adaptive filter was introduced.To do so,high frequency and low frequency of noise were filtered and system output would be more perfect.The numerical simulations showed that all improved algorithms in this paper were necessary and more effective. |
