| Abstract: | This paper describes the principle of MTC (Micro Tension Control). The rolling torque is obtained from the load observer, which improves the method of using current and voltage value of mill motor to calculate the rolling torque. The theory scheme, mathematic model and process control method are presented.The simulation result shows this system has several merits, such as stabilizing the calculated rolling torque,diminishing dynamic speed drop restore time and raising the performance of MTC. |
