Design of the temperature control system of solar cell lamination machine

The temperature control is the key step in the laminating process of solar cell lamination machine. The traditional controlling method is PLC temperature control. The method being used has some shortages such as high price, low control precision, and so on. In order to improve the control precision and its performance-price ratio, a new control system taking the double microcontroller (MCU) as its core is introduced in this paper. Based upon the system, the expert PID was designed to adjust the requirements of the temperature control. The method can adjust the temperature parameters and establish an accurate laminating temperature under the condition of changing temperature and different control targets. The practical operation results show that the controller has a better robustness and a higher control precision. In addition, it can adapt to an external changing condition, and has a strong anti-jamming capability.
