摘　　要：针对太阳能干燥和传统干燥相比具有节约能源、能量可再生的特点,设计了一套基于西门子PLC—200的太阳能干燥控制系统。该系统采用PID算法控制,用来提高系统的干燥精度,为进一步利用太阳能精准干燥农产品提供技术支持。According to the features of solar drying compared with conventional drying, such as energy saving, energy renewable, a solar drying control system was designed based on Siemens PLC--200. The system uses PID control algorithm to improve the stability and drying accuracy, which provides technical support for further using the solar energy in the precise drying of grapes and other agricultural products. Experimental results show that using PID algorithm to adjust the control system could realize real-time changes in drying the fruits and vegetables.
