Traditional Chinese medicine preparation process operation optimization method based on distributed model predictive control

Abstract

The invention discloses a traditional Chinese medicine preparation process operation optimization method based on distributed model predictive control, and the method comprises the steps: building an operation control process model of each link of a traditional Chinese medicine preparation process, and the operation control process model comprises a bottom layer process control loop model and an operation index and bottom layer controller output model; constructing a controller of a bottom-layer process control ring; designing a suboptimal set value of a controller of a bottom process control loop in the pharmaceutical process by adopting a data driving method; wherein the upper-layer operation control ring is updated by using a set value based on Q-learning according to a set value of an operation index and is transmitted to the bottom-layer process control ring through a zero-order retainer, and a controller of the bottom-layer process control ring gives a controlled quantity to control a controlled object to track a set value by solving an optimization problem. According to the method, the set value is updated by using the data of the operation process of traditional Chinese medicine preparation, and the bottom layer uses the DMPC to track the set value, so that the ideal value of operation index tracking is realized.

Description

technical field [0001] The invention relates to the field of intelligent decision-making, in particular to a method for optimizing the operation of a traditional Chinese medicine pharmaceutical process based on distributed model predictive control. Background technique [0002] As traditional Chinese medicine, traditional Chinese medicine cannot be taken directly. From the original plant to its medicinal use, a series of pharmaceutical techniques must be used to obtain the corresponding Chinese medicinal materials or herbal pieces for decoction or preparation. The entire pharmaceutical process includes steps such as pretreatment of Chinese medicinal materials, decoction, centrifugation, ultrafiltration, and concentration. Each step has specific optimal operating indicators, including but not limited to concentration. However, in the actual process of traditional Chinese medicine pharmaceuticals, we often cannot directly control the operating indicators such as concentration,...
