摘要

摘要: 为了克服流程工业运行优化中控制回路闭环系统的动态误差对运行优化性能的影响,本文针对一类工业过程提出了使运行指标实际值与目标值偏差和控制回路输出与设定值跟踪误差的二次性能指标极小化的运行优化反馈控制方法. 该方法由运行层设定值反馈控制和回路控制层设定值跟踪控制组成,其中设定值反馈控制采用基于LMI的模型预测控制,回路控制采用衰减率可调的带有积分项的状态反馈调节律. 本文给出了保证运行优化反馈控制闭环系统渐近稳定的充分条件,并开展了浮选过程运行优化反馈控制仿真实验,实验结果表明所提方法的有效性.

Abstract: In order to overcome the influence of the dynamic error of closed-loop control system on the operational process performance, an optimal operational feedback control method is proposed in this paper for a class of industrial processes by minimizing the quadratic performance index based on both the deviation between desired operational process index and actual value, and the tracking error between set-point and controlled plant output. This method employs a dual-layer control structure, consisting of the set-point feedback control in operation layer and the set-point tracking control in device layer. A model predictive controller using LMI is designed to dynamically give optimal set-points; an adjustable decay rate control using state feedback and error integral is employed for designing local controller to guarantee the tracking performance of the plant. In particular, a sufficient condition to guarantee the asymptotic stability of the whole closed-loop system is given. A simulation experiment in a flotation process is finally employed to demonstrate the effectiveness of the proposed method.
