基于多模型的動態(tài)矩陣控制Dynamic Matrix Con

針對動態(tài)特性隨工況而變化的復(fù)雜工業(yè)過程，本文提出一種基于多模型的動態(tài)矩陣控制。根據(jù)被控對象參數(shù)的變化范圍建立多個模型，同時建立以模型輸出誤差為變量的具有積分特點的指標(biāo)切換函數(shù)。在每一采樣時刻根據(jù)指標(biāo)函數(shù)與實際對象最接近的模型，并將基于此模型的控制器切換為當(dāng)前控制器。仿真結(jié)果表明對多工況的控制令人滿意。

Abstract：The purpose of this paper is to extend dynamic matrix control (DMC) to handle process with several operating levels based on multiple-model approach. A continuum of DMC controllers are developed which are supervised by a high-level switching logic. Performance index based on the error between the actual output and the predicted output is employed to generate the switching logic. Simulation results are given to show the effectiveness of this method.
