基于参数自整定的再热汽温解耦预测控制

Adaptive Dynamic Matrix Control with Design Parameters' Fuzzy Self-tuning for Reheated Steam Temperature System

预测控制由于其设计参数对控制系统性能的影响是以一种隐含的关系表达的，所以给设计者造成一定的选取困难。针对运行工况变化较频繁的强耦合时变大滞后锅炉再热汽温系统的特性，提出一种基于模糊逻辑自整定设计参数的自适应动态矩阵控制算法。由于该算法采用解耦控制算法的形式，使得参数调整更加灵活，对多变量系统更为有效。计算机仿真结果证实了其有效性。

Although DMC has many advantages in computation, control characteristics and robustness, its design parameters impose effects on the closed loop system in a hidden manner. This paper proposed an adaptive dynamic matrix control with design parameters' fuzzy self-tuning for the time-varying and large-delay coupling system with changing operation. Simulation of reheated steam temperature system of power plant boiler is given, its results demonstrate the effectiveness of the strategy proposed.
