Generally, to estimate the state variables of a plant with unknown parameters, an adaptive observer has been proposed. An adaptive observer identifies the unknown parameters and estimates the state variables. We propose an adaptive observer with a passive adaptive loop by use of an approximately inverse functional compensator. It is able to estimate the state variables without the unknown parameters identification, and the adaptive observer is not nesessary to satisfy the condition of richness of, the input signal. The constitution of the adaptive observer is simple, because it dose not have the identifier.<BR>In this paper, the construction, the stability, the estimation error, and the performance of the system are described and the simulated result of the proposed observer is given.
