Is the v-gap metric useful for industrial applications?

The v-gap analysis can be used to analyze the achievable robustness for a control system before designing any controllers. In its unweighted form, the v-gap promises powerful results. However, for practical applications, dynamic weights must be introduced, and then the results are with respect to this given choice of weights. For this weighted case, H∞ analysis provides a simpler alternative and yields less conservative results.
