中文摘要：

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，F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，从定性勺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。

英文摘要：

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.
