The Principle and Control Optimization Strategy of Aluminum Electromagnetic Roll-casting

This paper analyzes the basic structure and working principle of electro-magnetic inductor used in aluminum electromagnetic roll-casting production. The paper introduces the project of intelligent variable frequency power supply control system for aluminum electromagnetic roll-casting. And the hardware and software schemes of control system are also analyzed in the paper. The control system use fuzzy adaptive PID algorithm and design a specific waveform generator for the control object, which to optimize the system performance. The acting in the production shows that the control system has high control precision, good reliability and could improve the quality of aluminum roll-casting board obviously.
