Uncertainty levels are determined based on experimental data

摘要

In the robust control theory, the norm boundary of uncertainty set (i.e. the uncertainty level) is an important issue. When the level of uncertainty is too large, the results will be too conservative, and when the uncertainty is too small, the results will be too optimistic. Two methods for determining the uncertainty level based on experimental data are given in this paper. Method 1 can obtain the minimum model error bounds, but the calculation is complex. Method 2 is simple in calculation and suitable for engineering applications.
