uncertain system analysis -凯发k8网页登录

statistical and worst-case analysis of stability and performance

using robust control toolbox™, you can analyze the effect of plant model uncertainty on the closed-loop stability and performance of the control system. in particular, you can determine whether your control system will perform adequately over its entire operating range, and what source of uncertainty is most likely to jeopardize performance.

robust control toolbox provides functions to assess worst-case values for:

  • gain and phase margins, one loop at a time

  • stability margins that take loop interactions into account

  • gain between any two points in a closed-loop system

  • sensitivity to external disturbances

these functions also provide sensitivity information to help you identify the uncertain elements that contribute most to performance degradation. with this information, you can determine whether a more accurate model, tighter manufacturing tolerances, or a more accurate sensor would most improve control system robustness.
