Trinh, Hieu, Fernando, T. and Nahavandi, Saeid 2006, Partial-state observers for nonlinear systems, IEEE transactions on automatic control, vol. 51, no. 11, pp. 1808-1812.
This note deals with the design of reduced-order observers for a class of nonlinear systems. The order reduction of the observer is achieved by only estimating a required partial set of the state vector. Necessary and sufficient conditions are derived for the existence of reduced-order observers. An observer design procedure based on linear matrix inequalities is given. A numerical example is given to illustrate the design method.
