摘　　要：为了提高中药制剂的产品质量和生产效率,设计适合中药制剂自动提取的PID控制系统。介绍PID控制理论和中药制剂的控制流程,通过在中药制剂自动提取过程中对调节阀进行不同阶段的PID控制,使夹套压力稳定地保持在设定值上,从而使反应釜中的药液在不同的工艺阶段保持在不同的温度状态下。该系统已成功应用于企业中药制剂自动提取并取得了良好的效果。In order to enhance the traditional Chinese medicine preparation the product quality and the production efficiency,the design suits the traditional Chinese medicine preparation automatic extraction the PID control system.Introduced that the PID control theory and the traditional Chinese medicine preparation＇s control flow,through carries on the different period in the traditional Chinese medicine preparation automatic foliation to the regulating valve the PID control,causes the clamp cover pressure maintains in stably the setting value,thus causes in the reaction still the solution temperature,in the different craft stage maintains under the different temperature condition.This system has succeeded applies withdraws and has made the good progress automatically in the enterprise traditional Chinese medicine preparation.
