以高纯精馏塔为例，阐述了结垢不良的物理原因及其对控制系统设计和性能的影响。结果表明，通过简单的回路成形技术(使用奇异值)不能获得可接受的性能/鲁棒性折衷，并且对模型不确定性的良好理解对于鲁棒控制系统的设计是至关重要的。物理激励的不确定性描述(执行器不确定性)被转化为H/超无穷//结构奇异值框架，这被证明是分析和理解复杂现象的有力工具。>；
Using a high-purity distillation column as an example, the physical reason for the poor conditioning and its implications on control system design and performance are explained. It is shown that an acceptable performance/robustness tradeoff cannot be obtained by simple loop-shaping techniques (using singular values) and that a good understanding of the model uncertainty is essential for robust control system design. Physically motivated uncertainty descriptions (actuator uncertainties) are translated into the H/sup infinity //structured singular value framework, which is demonstrated to be a powerful tool to analyze and understand the complex phenomena. >
