摘要
介绍了一种真空冷冻干燥试验仪的温度控制器设计,以AT89C52为控制核心,选用PT100传感器,MC14433A/D,利用增量式PID算法来完成对电机执行机构的运动控制,从而实现温度的精确控制。
A Temperature Controller for the Tester of Vacuum Freeze-dring Technique is designed Based on Single-chip Microcomputer AT89C52, the controller makes use of the FF100 sensor, MC14433A/D and the increasing PID control method to complete the motor controlling, and then make the temperature to be exactitude controlled.
