Control Plan
- Jan 04, 2018 -

Automatic wind ring is an online real-time control system, the system is controlled by the object is distributed in the wind ring on a number of motors. The cooling air sent by the fan is distributed to each duct by the constant pressure of the wind chamber and the motor is driven by the motor for opening and closing movement to adjust the size of the tuyere and the air volume to change the cooling effect of the film blank at the die outlet. So as to control the thickness of the film. From the control process, there is no clear relationship between the change of the thickness of the film and the amount of motor control. The non-linear and irregular change of the thickness and the amount of control at different positions of the film and the valve varies with each valve The influence on adjacent points is very big, and the adjustment is lagged so that the different moments are related to each other. For this highly nonlinear, strongly coupled, time-varying and control-uncertain system, the exact mathematical model is almost impossible Even if the mathematical model can be established, it is also very complicated and difficult to solve so that it has no practical value. However, the traditional control is better than the control model, while the control of highly nonlinear, uncertain and complicated feedback information is poor Even helpless. In view of this we have chosen the fuzzy control algorithm. At the same time, the method of changing the fuzzy quantitative factor is better adapted to the change of system parameters.
