In this paper we show that it has considerable advantages to use polynomial approximations obtained with an interpolation formula for derivation of state estimators for nonlinear systems. The estimators become more accurate than estimators based on Taylor approximations; yet the implementation is signiicantly simpler as no derivatives are required. Thus, it(More)
