| Abstract: | This paper introduced a kind of control system for aluminum electromagnetic rapil roll-casting based on SPWM technology. The working principle, structure of hardware and software, and control mode of system were analysed, furthermore, the control system was tested. The experiment show that the system can control the composite magnetic, produced by the inductor; which can satisfied the requirement of alumimum electromagnetic rapid roll-casting, and the system have high control precision, good reliability and dynamic response. |
