An experimental platform for operation control of flotation process

Abstract

The invention provides an experimental platform for flotation process running control, and realizes a function of simulating the flotation process and a function of monitoring the flotation process, so as to achieve the purpose of simulating an advanced control algorithm of the flotation process. In the experimental platform, a process monitoring computer runs a process monitoring system, and a virtual object computer runs a virtual object system; the virtual object system realizes the real-time running of a bottom layer mechanism model and a running layer model of the flotation process, and realizes the simulation of dynamic characteristics of an actual flotation process object; different identification algorithms are selected for different application scenes to estimate unknown parameters in the bottom layer mechanism model and the running layer model of the flotation process; and the process monitoring system utilizes the virtual object system, a real PLC program and a controller are adopted to control a bottom layer loop of the virtual object, the tracking of optimized set values of economic indexes is realized, a semi-physical simulation experiment of the flotation process isrealized, and a contrast test of different control algorithms is completed.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an experimental platform for operation control of a flotation process. Background technique [0002] The purpose of the flotation process is to achieve the production effect as high as possible, as low as possible, and as low as possible under the influence of adjusting and controlling the process variables under the premise of safety, stability and reliability. High economic benefit. Because the process has the characteristics of high risk, long production cycle, relatively high cost of physical equipment and its experiments, and because the current flotation production process is still under manual control, due to the influence of changes and disturbances in boundary conditions such as ore properties , manual operation cannot be adjusted in time and accurately, and it is difficult to ensure that the control target value is within the ideal range, which af...

Problems solved by technology

Because the process has the characteristics of high risk, long production cycle, relatively high cost of physical equipment and its experiments, and because the current flotation production process is still under manual control, due to the influence of changes and disturbances in boundary conditions such as ore properties , manual operation cannot be adjusted in time and accurately, and it is difficult to ensure that the control target value is within the ideal range, which affects the concentrate grade and metal recovery rate

Due to the crucial safety status of the flotation process in mineral processing production, it is determined that the engineering verification of advanced control methods cannot be carried out on site
