Locally Convergent Nonlinear Observers
We introduce a new method for the design of observers for nonlinear systems using backstepping. The method is applicable to a class of nonlinear systems slighter larger than those treated by Gauthier, Hammouri, and Othman [IEEE Trans. Automat. Control, 27 (1992), pp. 875– 880]. They presented an observer design method that is globally convergent using high gain. In contrast to theirs, our obser...
متن کاملOn Performance Improvement of an Output Feedback Control for Non-Uniformly Observable Nonlinear Systems
We enhance the recently proposed output feedback stabilization scheme by the authors. One of the major contributions of the previous work is the presentation of a constructive way to relax the uniform observability condition, which has been frequently used in order to establish a nonlinear semi-global separation principle, by assuming the existence of a specific input signal (universal input) t...
متن کاملObserver Design for a class of uniformly observable MIMO nonlinear systems with coupled structure
A high gain observer is synthesized from a canonical form that characterizes the class of uniformly observable systems. Two main contributions are to be emphasized: the first is related to the considered structure of the canonical form which does not assume a complete triangular structure. That is, each block may contain nonlinearities which depend on the whole state. The second main contributi...
متن کاملInput Selection in Observer Design for Non-Uniformly Observable Systems
In this paper the problem of inputs in observer design for systems which are not uniformly observable is considered. It is emphasized how it amounts to a control problem, which can be solved in a general way by some appropriate optimization approach. This is illustrated on the basis of a quite general Kalman-like observer form possibly with high gain, as well as related simulation results on an...
متن کاملUsing Tracking Differentiators in Designing Nonlinear Disturbance Observers for Uncertain Systems
Using Tracking Differentiators in Designing Nonlinear Disturbance Observers for Uncertain SystemsNaser Kazemzadeh, Saeed BarghandanAbstractIn the present paper, a practical designing method has been proposed for a novel class of NDOs based on TD. Such NDOs can nearly estimate all uncertain disturbances (specifically disturbances without prediction information). Regarding the outstanding perform...
