High Nonlinearity And Strong Coupling
Apr 14, 2017

The automatic wind ring is an on-line real-time control system, which is controlled by a number of motors distributed in the wind ring. The cooling airflow sent by the blower is allocated to each duct by the wind chamber constant pressure, and the valve is operated by the motor to adjust the air volume and the cooling effect of the film billet in the Die head, and thus control the thickness of the film. From the control process, the film thickness change and the motor control between the clear relationship between the different thickness of thin film and valve different position thickness change and control amount of non-linear change between the path, each adjustment of the adjacent point of the impact of a valve is very large, and adjustment has hysteresis, So that the different moments are interconnected, for this highly nonlinear, strong coupling, time-varying and control uncertainty system, its precise mathematical model is almost impossible to establish, even if the mathematical model can be established, it is very complex, difficult to solve, so that no practical value, and the traditional control of the control model to determine the effect is better, and for high nonlinearity, uncertainty, complex feedback control effect is very poor or powerless. In view of this, we chose the fuzzy control algorithm. At the same time, the change of fuzzy quantization factor is used to better adapt to the change of system parameters.
