First, for state estimation problem of the linear stochastic systems with uncertainties in both the state matrix and the noise matrix, a new satisfactory estimator is constructed with stochastic theory, which can guarantee that estimator error system with bounded perturbed model parameter satisfies the constraint indexes that is given. Thus a sufficient condition of solving satisfactory estimation is obtained; secondly, the algorithm of designing satisfactory estimator is presented by analysis.
