Control Scheme Of Blow Moulding Machine

The automatic air ring is an on-line real-time control system, and the system is controlled by a number of motors distributed on the wind ring. The cooling airflow sent by the fan is distributed to each duct through the constant pressure of the wind-ring chamber, by the motor-driven valve for opening and closing movement to adjust the size of the tuyere and air volume, change the cooling effect of the film at the die, so as to control the thickness of the film, from the control process, the film thickness change and motor control can not find a clear relationship between.

The different thickness of thin film and the different position of the valve between the thickness of the change and the control of the non-linear change, the impact of each valve on the adjacent point is very large, and the adjustment has hysteresis, so that the different time is interrelated, for this highly nonlinear, strong coupling, time-varying and control of uncertainty system, The precise mathematical model is almost impossible to establish, even if the mathematical model can be established, it is very complicated and difficult to solve, and it has no practical value, while the traditional control has better control effect on the control model, and for the high nonlinearity, uncertainty, complex feedback information control effect is very poor or even powerless. In view of this we have chosen the fuzzy control algorithm. At the same time, change the fuzzy quantization factor to adapt the system parameter change better.
