Multivariable feedback control : analysis and design 一书中的所有MATlab程序。是学习鲁棒控制的好材料。

Fluidized bed combustion (FBC) boilers have received increasing attention in recent decades. Th erosion issue on the water wall is one of the most common and serious faults for FBC boilers. Unlike direct measurement of tube thickness used by ultrasonic methods, the wastage of water wall is reconsidered equally as the variation of the overall heat transfer coeffient in the furnace. In this paper, a model-based approach is presented to estimate internal states and heat transfer coeffient dually from the noisy measurable outputs. Th estimated parameter is compared with the normal value. Thn the modifid Bayesian algorithm is adopted for fault detection and diagnosis (FDD). Th simulation results demonstrate that the approach is feasible and effctive.

锅炉过热汽温的动态特性会随运行工况发生较大变化,传统的控制方法难以达到理想的控制性能。该文基于线性自抗扰控制器设计串级优化控制方案,根据现有的比例-积分-微分(PID)控制器参数计算自抗扰控制器参数初值,进而基于改进的优化指标,采用果蝇算法优化出一组适用于不同工况的固定控制器参数。仿真结果表明:该方案能够很好地平衡快速性与稳定性的矛盾,且具有更好的性能鲁棒性。
