Abstract

The invention discloses a substance mixing intelligent system, which is characterized in that the system is composed of a parameter acquisition and control platform and a substance mixing adjustment subsystem, the system realizes the parameter detection of a mixed object and the adjustment of a substance mixing process, and reliability and accuracy of the process of adjusting the mixed substance are improved; according to the influence of problems of inaccuracy, poor robustness and the like of an existing gas or liquid mixing ratio control system on the performance of the gas or liquid mixing ratio system, problems of poor robustness, slow response speed and the like of the gas or liquid mixing ratio system are effectively solved.

Description

technical field [0001] The invention relates to the technical field of gas or liquid material mixing automation equipment, in particular to an intelligent material mixing system. Background technique [0002] The gas or liquid mixing ratio system refers to a type of system that obtains a specific gas or liquid according to the mixing theory. At present, the gas or liquid mixing ratio system has been widely used in the fields of biological science research, environmental monitoring, and instrument control and calibration. The various technical parameters of the mixing ratio system, especially the low precision and response time of the mixing ratio system, put forward higher standards. Since the mixing ratio system has time-varying nonlinearity and it is difficult to establish an accurate mathematical model, only the traditional PID controller will have a response Due to the shortcomings of slow speed and low system precision, it is difficult to achieve the ideal control effec...
