Modeling and simulation of the double armatures motor speed control system for 2030 tandem cold rolling mill are predigested to that of a single armature motor speed control system equivalently, so the rapidity and real-time performance of the simulation for tandem cold rolling mill are improved to some extent. Through the detailed analysis and calculation, the model structure and parameters of each tache of the dc motor speed control system with field weakening and speed self-adjusting are obtained for 2030 tandem cold rolling mill. The simulation results show that output response of the established speed control system is consistent with the one from real spot, so it is demonstrated that the established model for speed control system is accurate. The model structure of the speed control system is complete and it has great universality.
