The Study and Experiment of Advance Control of Chaotic Vibration Mill with High Vibration Intensity Based on SCM (II) — The System Construction and the Controlling Methods

Abstract

A intelligent variable frequency amplitude reduction advance control system whose single-chip-microcomputer act as the core controller is built, and the vibration frequency curve with multiple wave variable sine increase and decrease periodic cycle is applied as the input frequency curve, which made the vibration mill have multiple frequency and amplitude. The control methods are studied, and the operation program is debugged. By using the sensor signal amplification, A/D conversion, on-line monitoring, data mining, and the forecast of the extreme value point of the vibration intensity and its distribution, and then by conducting the judgment, detection, correction and real-time feedback of constraint condition to achieve advance control of vibration intensity over-limit and over-time.
