Water pressure prediction and control method for automatic cleaning process of herbal medicine

Abstract

The invention discloses a water pressure prediction and control method for an automatic cleaning process of herbal medicine. In order to solve the problem that the water pressure in the automatic cleaning process of herbal medicine is limited by the performance of a water pump itself, the pre-determinated water pressure cannot be quickly and accurately achieved, a frequency/unit-step response model is adopted in the automatic cleaning process of herbal medicine. By minimizing a cumulative function of the water pressure tracking deviation over a future period of time and the change amount of the input voltage frequency of the water pump, the size of the input voltage frequency of the cleaning pump in the automatic cleaning process of herbal medicine is calculated in real time, so that the optimized automatic control of the water pressure tracking target value of the automatic cleaning process of herbal medicine is realized. According to the water pressure prediction and control method for the automatic cleaning process of herbal medicine, the method is intuitive, simple in design, and easy to realize.

Description

technical field [0001] The invention belongs to the field of automatic control of the production process of decoction pieces of traditional Chinese medicine, and relates to a water pressure predictive control method for the automatic cleaning process of decoction pieces of Chinese medicine and medicinal materials. Background technique [0002] Chinese herbal decoction pieces are traditional Chinese medicines that can be directly used in TCM clinics after being processed according to the theory of traditional Chinese medicine and traditional Chinese medicine processing methods. Compared with taking western medicine, the side effects in the human body are smaller. Chinese herbal decoction pieces are effective in treating chronic diseases, immune diseases and It has unique curative effects in health care, longevity and other aspects. Due to the different varieties and origins of traditional Chinese medicines, their shapes and surface characteristics are different, and the conte...
