Abstract: Based on the H∞ tracking performance, a synthesis procedure is given to the design of a class of adaptive observers. Designing the fault adaptive laws through comparison, several factors influencing the performance of fault estimation of the class of adaptive observers are obtained. The fault estimation error of an adaptive observer thus designed is irrelevant to the fault amplitude and it can be tuned to be as small as possible by adjusting H∞ tracking performance index. A simulation exemplifies the effectiveness of the analysis results.
