摘要/Abstract

摘要： 模型预测控制算法（MPC）存在设定点控制与区间控制两种策略，区间预测控制较之设定点控制在技术上具有先进性。目前，主流的预测控制软件技术均采用双层结构，即上层稳态优化计算最优设定点，下层动态控制负责动态跟踪最优设定点。从过程稳态的角度出发，分别对区间预测控制和双层结构预测控制进行了机理分析，从定性与定量两个方面比较了这两者的异同点，提出并证明了两者的一致性条件。论述了双层结构预测控制较之单层结构下的区间控制更具先进性。

关键词: 模型预测控制, 区间控制, 稳态优化

Abstract: There exist two different strategies in model predictive control (MPC),i.e.,set-point control and zone control.In comparison,zone MPC is thought to be a better strategy.However,there exists an improved set-point control strategy,i.e.,double-layered MPC,which computes set points through the steady-state target calculation in the same control cycle.In this paper,from the aspect of process steady state,the principles of zone control and double-layered MPC are analyzed.We discuss the differences and similarities between the two strategies both qualitatively and quantitatively,and prove that the two strategies are consistent in a certain context.Simulation results are given to validate the conclusion.

Key words: model predictive control, zone control, steady-state optimization
