Abstract Economic model predictive control (EMPC) is a model-based control scheme that integrates process control and economic optimization, which can potentially allow for time-varying operating policies to maximize economic performance. The manner in which an EMPC operates a process to optimize economics depends on the process dynamics, which are fixed by the process design. This raises the question of how process and EMPC designs interact. Works which have addressed process and control design interactions for steady-state operation have sought to simultaneously develop process designs and control law parameters to find the most profitable way to operate a process that is able to prevent process constraints from being violated and to optimize capital costs in the presence of disturbances. Because EMPC has the potential to operate a process in a transient fashion, this work first focuses on how EMPC and process design interact in the absence of disturbances. Using small-scale process examples, we seek to understand the fundamental nature of the interactions between EMPC and process design, including how these interactions can impact computational complexity of the controller and the design procedure. We subsequently utilize the insights gained to suggest controller design variables which might be considered as decision variables for a simultaneous process and control design problem when disturbances are considered.

经济模型预测控制下控制与过程设计的相互作用

摘要 经济模型预测控制 (EMPC) 是一种基于模型的控制方案，它集成了过程控制和经济优化，它可以潜在地允许时变操作策略以最大化经济性能。EMPC 操作流程以优化经济性的方式取决于流程动态，而流程动态是由流程设计确定的。这就提出了流程和 EMPC 设计如何相互作用的问题。针对稳态操作的过程和控制设计交互问题的工作寻求同时开发过程设计和控制律参数，以找到最有利可图的方法来操作能够防止违反过程约束并优化资本成本的过程在有干扰的情况下。由于 EMPC 有可能以瞬态方式运行过程，因此这项工作首先关注 EMPC 和过程设计如何在没有干扰的情况下相互作用。使用小规模过程示例，我们试图了解 EMPC 和过程设计之间相互作用的基本性质，包括这些相互作用如何影响控制器和设计过程的计算复杂性。我们随后利用获得的见解来建议控制器设计变量，当考虑干扰时，这些变量可能被视为同时处理和控制设计问题的决策变量。我们试图了解 EMPC 和过程设计之间相互作用的基本性质，包括这些相互作用如何影响控制器和设计程序的计算复杂性。我们随后利用获得的见解来建议控制器设计变量，当考虑干扰时，这些变量可能被视为同时处理和控制设计问题的决策变量。我们试图了解 EMPC 和过程设计之间相互作用的基本性质，包括这些相互作用如何影响控制器和设计程序的计算复杂性。我们随后利用获得的见解来建议控制器设计变量，当考虑干扰时，这些变量可能被视为同时处理和控制设计问题的决策变量。
