A Variable Structure Observer Based Control Design for a Class of Large scale MIMO Nonlinear Systems
This paper fully discusses how to design an observer based decentralized fuzzy adaptive controller for a class of large scale multivariable non-canonical nonlinear systems with unknown functions of subsystems’ states. On-line tuning mechanisms to adjust both the parameters of the direct adaptive controller and observer that guarantee the ultimately boundedness of both the tracking error and tha...
متن کاملA nonlinear canonical form for reduced order observer design
This paper presents a nonlinear canonical form which is used for the design of a reduced order observer. Sufficient and necessary geometric conditions are given in order to transform a special class of nonlinear systems to the proposed nonlinear canonical form and the corresponding reduced order observer is analyzed.
متن کاملReduced-order observer design for descriptor systems with unknown inputs
A new method for the design of reduced-order observers for descriptor systems with unknown inputs is presented. The approach is based on the generalized constrained Sylvester equation. Sufficient conditions for the existence of the observer are given.
متن کاملReduced order disturbance observer for discrete-time linear systems
In the paper, an output-based disturbance observer of reduced order is presented for a class of discretetime linear systems. First, a general form of a disturbance observer is proposed when full states are available. Then, by combining a state function estimator of minimal order, an output-based disturbance observer is derived. The existence condition will be formulated in the form of a static ...
متن کاملOrder Extension of Nonlinear Systems for Observer Design under Reduced Observability Properties
Nonlinear unforced systems of order n with reduced observability properties are considered. This reduction concerns the fact that the r-observability map is injective only for r > n. An immersion into a higher order system containing the original system coordinates is proposed, such that estimation of the original states of the system is simplified. Approximate or event-based observers are prop...
