Embodiment Construction

[0066] Take the waste treatment gasifier as an example:

[0067] The gasifier for waste treatment is a common chemical batch reaction process, which contains many process variables, and the model proposed by the present invention can be effectively used.

[0068] Step 1. Establish a system model of the reaction process of the waste treatment gasifier. The specific steps are:

[0069] 1.1 Obtain the measurement data of the garbage disposal process, expressed as:

[0070]

[0071] v m =[x 1m x 2m …x Nm ] T (m=1,2,...,M)

[0072] In the formula, X represents the data array obtained in the process, N represents the number of data samples in the process, M represents the number of process variables, m represents the mth process variable in the process, and x 1 x 2 …x N Represent the 1st, 2nd,...,N sample data vectors, v 1 v 2 … v M represent the 1st, 2nd,...M process variables respectively. T stands for transpose notation.

[0073] 1.2 Centralize the data in step...

Abstract

The invention discloses a method for modeling and monitoring the batch process of chemical engineering. The method comprises the following steps: collecting data in a chemical engineering process, andprocessing the data to obtain data with most processing information; establishing a process model with the processed data; and providing a monitoring method for the model to ensure stable operation of the chemical engineering batch process. By utilizing the method, process state changes of a reactor can be well tracked, the uncertain of the model can be made up to a certain extent, and the systemperformance can be improved.

Description

technical field [0001] The invention belongs to the technical field of automation and relates to a novel modeling and monitoring method of chemical batch process. Background technique [0002] With the acceleration of the globalization process, my country's industrial technology has entered a stage of comprehensive development. The chemical batch process is playing an increasingly important role in our country's industrial process and has received more and more attention. A large amount of data will be generated in the chemical batch process, and it is impractical to process all the data. Therefore, it is necessary to propose a method to process these data in order to obtain effective data that can model the chemical batch process. [0003] System control is an important part of the chemical batch process. Whether the system is stable or not directly determines the quality of the product and the level of output. Therefore, proper modeling of chemical batch processes to tra...
