WebGap Metrics in Robust Design To make use of the gap metrics in robust design, you must introduce weighting functions. In the robust performance formula, replace P by W2PW1 , and replace C by W 1 − 1 C W 2 − 1. You can make similar substitutions for P1 , P2, C1 and C2. WebJan 1, 2014 · The gap metric was introduced by Zames and El-Sakkary for this purpose. Its study climaxed in an award-winning paper by Georgiou and Smith. A modified gap, called the ν-gap, was later discovered by Vinnicombe and was shown to have advantages. With these metrics in hand, robust stabilization issues can be nicely addressed.

WebDefinition 1. Robustness—in the scope considered in this survey—refers to the ability to cope with variations or uncertainty of one’s environment. In the context of reinforcement learning and control, robustness is pursued w.r.t. specific uncertainties in system dynamics, e.g., varying physical parameters.
