层压是太阳能电池组件生产的关键步骤,层压机将敷设好的电池加热使EVA融化,使电池、玻璃和背板粘压在一起。层压温度是层压机重要的被控参数之一,环境温度变化和电网电压波动都会影响控制温度,常规PID控制难以达到较高的控制精度。为了实现较高的控制精度,采用MCU AT89C51开发基于模糊PID的温度控制系统,做了Matlab仿真实验,比较模糊PID控制系统与常规PID控制系统的阶跃响应曲线。实验证明模糊PID控制系统比常规PID控制在响应速度和超调量方面都具有明显优势,对于提高层压机的温度控制精度及实时控制具有较好效果。

Laminating is a key step of solar cell module production.Laminating machines heat to melt the EVA,and press the battery,glass and glued back together.Laminating temperature is one of the important parameters of the charged,the environment temperature and voltage fluctuations will affect the control of temperature.Conventional PID control is difficult to achieve high control accuracy.In order to achieve high control accuracy,a fuzzy PID temperature control system is developed using AT89C51 Microcontroller.In Maltlab simulation,we compare the step response curves of the conventional PID control system with fuzzy PID control system.Curves shows that the fuzzy PID control system has obvious advantages than the conventional PID control in terms of speed and overshoot.The fuzzy PID temperature control system has better results in accuracy and real-time control of the laminating temperature control.
