Abstract: The problem of state observer design for a class of multi-input multi-output affine nonlinear systems is investigated. Based on the input-output linearization method, a new approach of state observer design for multi-input multi-output affine nonlinear systems is proposed. Sufficient conditions that guarantee the state observation error to converge to zero asymptotically are obtained. Finally an example is given to show the validity of obtained results. -
