摘要
磨矿过程是选矿过程中的关键工序,其运行品质对于提高选矿厂产品质量和生产率至关重要。该过程具有非线性、大时滞、慢时变、关键工艺参数无法在线测量等综合复杂特性,其控制、优化和软测量技术的研究具有重要意义和相当难度。为了降低现场调试的成本和风险,如何在实验室中建立工程化的磨矿过程控制仿真系统成为具有重要实用价值的研究课题。本文设计和开发了磨矿过程控制仿真实验平台。提出了由真实的磨矿过程控制系统和虚拟生产组成的磨矿过程控制仿真实验平台的体系结构,可以为磨矿过程的控制和优化算法提供工程化的实验环境。
Grinding process is a critical procedure of mineral process, and its running character is extremely important for the productivity and quality improvement. It is comprehensive and complicated characteristics of nonlinearity, large time -delay, slow time -varying and so many key engineering parameters which can not be detected online. It is dramatically significant and difficult to study the control algorithms, the optimization algorithms and the soft censor techniques for grinding process. In order to decrease the cost and risk of practical debugging, how to establish a control simulation system of grinding process for engineering is an issue which has greatly practical value. The simulation experiment platform for grinding process control is designed and developed. The general structure of the platform including real control system and virtual production plant is proposed. Thus, a kind of engineering experiment environment is provided for control and optimization algorithms.
