Embodiment Construction

[0055] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] The ADRC model establishment principle of the present invention is:

[0057] On the basis of the simplified model of the dynamic batching system, the ADRC controller of the system is designed. First, the simplified model of the dynamic batching system is converted to a certain extent. From the process model, the relationship between the input f and the output of the batching system changes. for:

[0058] Q G = 2 πR D R G R J whρf = K * ρf

[0059] in, is the constant related to the structure of the dynamic batching sy...

Abstract

The invention relates to a dynamic batching active-disturbance-rejection control method, and belongs to the field of a building material dynamic batching technology. The method comprises the following steps: step one, establishing a dynamic batching system motor frequency and material flow model; step two, establishing a belt scale material impact model in a dynamic batching process; step three, establishing a dynamic batching system weighing model; and step four, through combination with the dynamic batching system motor frequency and material flow model in step one and the belt scale material impact model in step two and the dynamic batching system weighing model in step three, establishing a dynamic batching system active-disturbance-rejection control model by use of a modern advanced active-disturbance-rejection control technology so as to realize dynamic batching active-disturbance-rejection control. According to the invention, through combination of a mechanism analysis and a modern advanced control technology, the ratio precision of the dynamic batching process is controlled, accurate batching of a building material dynamic batching system is realized, and the method has high robustness and high anti-interference performance in application of the dynamic batching system and thus has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of dynamic batching, and relates to a dynamic batching active disturbance rejection control method, in particular to a dynamic batching active disturbance rejection control method realized by a simplified model and advanced control technology. Background technique [0002] With the development and progress of science and technology, in today's industrial product production, most of the products are made of several raw materials mixed in a certain proportion, such as cement, feed, chemical fertilizer, food, medicine, etc. This kind of dynamic batching system, which mixes various raw materials according to the preset ratio, is widely used in the industrial production process. It dynamically weighs and batches ingredients in different batching systems according to the prescribed batching ratio of different raw materials. of. [0003] In construction, feed processing, food processing, pharmaceutical, chemical a...
