摘　　要：温度是影响整个太阳能电池板真空薄膜灌封系统正常工作的关键因素之一。为实现对薄膜灌封系统多环节温度的精确控制,使薄膜灌注料在整个系统中处于良好的流动性,基于参数自整定模糊PID的控制策略,采用传统PID控制和模糊理论相结合的方法设计了模糊自整定PID控制器,并运用Matlab软件对分析过程进行仿真。仿真结果表明,该温控系统的动态响应特性和稳态精度达到了预期要求,并具有一定的鲁棒性,能满足高精度温度控制的场合。Temperature is one of the key factors affecting normal operation of the vacuum membrane pouring and encapsulation system for solar battery plates.In order to realize accurate temperature control for multiple sections in pouring and encapsulation,and make the membrane pouring material features excellent fluidity in the whole system,by adopting parameter self-tuning fuzzy PID control strategy,and combining traditional PID control and fuzzy control theory,the fuzzy self-tuning PID controller is made.By using Matlab,the analytic process is simulated.The result of simulation indicates that the dynamic response characteristic and static accuracy of the system reach expected requirements,the system features certain robustness and satisfies requirement of high accurate temperature control.
