提出了一种根据工厂先验信息以最少的附加不确定性进行建模的方法。可行系统集被定义为由一类微分方程控制的所有系统的集合，该微分方程具有未知输入和输出算子的某些范数界限以及部分已知的特征参数。然后，包括可行集的非结构化不确定性类在频域中用最小的加性扰动来表征。演示了有限维补偿器设计的示例，以说明所提出方法的有用性。
An approach is presented for modeling with least additive uncertainty from a priori information of a plant. A feasible set of systems is defined as the set of all systems governed by a class of differential equation with certain norm bounds of unknown input and output operators as well as partially known eigenparameters. Then an unstructured uncertainty class including the feasible set is characterized with least magnitude of additive perturbation in frequency domain. An example of finite dimensional compensator design is demonstrated to illustrate the usefulness of the presented approach.
