Challenges of Optimal Control for Plant-wide Production Processes in Terms of Control and Optimization Theories
-
摘要: 从控制系统的观点描述了生产制造全流程的控制与运行管理流程, 分析了表征产品的质量、产量、成本、消耗等相关的综合生产指标与控制系统动作之间的联系, 回顾了涉及的控制与优化的研究成果. 从基于数学模型、基于数据和基于模型与数据相结合的角度综述了控制与优化方面的研究现状. 在此基础上分析了生产制造全流程优化控制对过程控制与运行优化、以及控制系统实现技术的挑战, 分析了实现生产制造全流程优化控制应开展的研究内容.Abstract: This paper describes the control and operationalmanagement of plant-wide production processes from a viewpoint ofcontrol system, and analyzes the relationship between the controlsystem actions and the multiple global production indices thatcharacterise quality, yield, costs, consumptions, etc. The existingresearch results in the aspects of control and optimization arereviewed. From the angles of mathematical model-based, data-based,and the combination of mathematical model with data-based, thestate-of-the-art of control and optimization are summarized. On thebasis of the above review, this paper also analyzes the challengingof the optimal control for plant-wide production processes in termsof process control, operational optimization and the realizationtechnique of the control systems. Finally, some research topics arediscussed, which may be developed to realize the optimal control ofthe plant-wide production processes.
