Iterative Learning in Electromagnetic Vibrating Machine Amplitude Control

The iterative learning control is applied to electromagnetic vibrating machine in blending system, which executes the same task repeatedly over a finite time-interval. The iterative learning controller of electromagnetic vibrating machine amplitude is provided and the convergence analysis is also given. This technique uses the operation information in blending system and enables the tracking performance better from operation to operation without any model information. It also can suppress the effect of repetitive external disturbance. The experiment results show that the desired amplitude can be acquired and it fits to high precise blending system.
