... defined as the difference between and the measurement instruments on the system. For test estimates (V TH and R TH) and the actual Thevenin equivalent purposes, noise is added to the simulated measurements and parameters. The controlled perturbation is achieved on the represents the compounded effects of the total uncertainty. actual system by varying ...
