MOTOR LOAD TORQUE CALCULATING AND MODELING FOR SPEED CONTROL SYSTEM OF THE 2030 TANDEM COLD ROLLING MILL

Abstract

Abstract: Based on knowing well the DC motor speed control systems for 2030 tandem cold rolling mill, modeling and simulation for a double armature motor speed control system is predigested to that for a single armature motor speed control system equivalently. The physical model of the DC motor speed control system with field weakening and speed self-adjusting is established for 2030 tandem cold rolling mill. The model structure and parameters of each tache of the speed control system are obtained through the detailed analysis and account. The on-line calculation formula of the motor load torque is given for the speed control system of the tandem cold rolling mill. The simulation and actual measured results combining the spot status data show that the established model for speed control system is accurate, and the on-line calculation formula of the motor load torque is feasible.
