作者给出了一些见解H/子无穷大/权重选择从过程控制的角度来看，重点是不确定性建模。他们研究如何将参数增益延迟的不确定性转换为频率相关的权重指定范数有界的不确定性。他们假设一个参数增益延迟不确定性集作为真正的不确定性。然后，他们试图最小化一个复杂的添加剂扰动所产生的不确定性集，覆盖了真实的集。此外，针对所考虑的例子问题，设计了μ-最优控制器.仿真结果。<<ETX>>
The authors give some insight into H/sub infinity /-weight selection from a process control perspective, with emphasis on uncertainty modeling. They study how to transform parametric gain-delay uncertainties into frequency-dependent weights specifying norm-bounded uncertainties. They postulate a parametric gain delay uncertainty set as the true uncertainty. They then try to minimize an uncertainty set generated by a complex additive perturbation which covers the true set. In addition, mu -optimal controllers are designed for the example problem considered. Simulation results are presented.<<ETX>>
