摘 要：In Section 2.2.5.4 it was indicated that, in general, for nonlinear parametriza-tion of the system responses, optimum experimental conditions strongly depend on the unknown parameter values which only have to be estimated. This causes one of the main complications related to the determination of optimal experimental conditions. A common approach is then to design the experiment for some reasonable nominal parameter values whose knowledge is a prerequisite for applying the locally optimal sensor location methods described in the previous chapters. Since the uncertainty of those nominal values is not taken into account, practical application of such procedures is limited to situations when system responses change slowly in the set of admissible parameters.
