Abstract


With the development of the national economy, the high-speed development. ERW (high frequency resistance) welding steel, mold steel and other industries In order to improve the safety of products and to save energy at home and abroad, all steel plate has been toward the development of light weight and high strength, the development of high-strength sheet has good prospects for development. Slitting Slitting is a necessary process for production of high-strength steel, a steel hot rolling finishing slitting line in order to adapt to the needs of the production, it is necessary to transform their old equipment. In this paper, the problem exists in a steel hot-rolled finishing the slitting line production process background, power testing key equipment slitting line, calculated means of system transformation based on, by changing the control mode, speed matching, re-create the tension control model to optimize the system to reach the production requirements. At the same time, the whole line control using Siemens S7-300, of ET200S series PLC and DC transmission equipment 6RA70 constitute a distributed computer control system based on PROFIBUS-DP. In order to guarantee the stability of the product quality and production process. The the rolling technological requirements between the pinch rolls and straightening rack should remain stable tension. Tension system is a nonlinear, time-varying process with a fixed set of PID parameters can not be a good control system. Fuzzy PID control is a kind of intelligent control, its biggest advantage is not dependent on the accurate mathematical model of the controlled object has strong robustness, adjust object parameter change, and thus in the field of electric drive has been relatively mature. For the above reasons, taking into account the engineering practicality, the topics on the use of fuzzy PID control as a transmission system control programs conducted in-depth research explore. In the control algorithm, using the online rules since adjustments \parameter self-tuning control strategy of fuzzy control mechanism, and the scale factor to online tuning the performance of the control system, to obtain the appropriate value, so that the performance of the system at a satisfactory level. Finally, done with MAIALB software simulation of the control system, the response curve of the draw tension model under different strategies.
