| Research Abstract |
General approach for designing nonlinear observer does not exist so far. In this research, two approaches are proposed for the nonlinear observer design. The first one employs the state-dependent linear representation and uses the result of obtaining analytic solution for linear Sylvester equations. Observers with this approach have an advantage in actual implementations with its analytic representation.
The other approach tries to solve nonlinear Sylvester equation based on invariant manifold computation. This method uses the result of N. Sakamoto for invariant manifold computation theory.
