Estimation of Asymptotic Stability Regions of Nonlinear Systems by Use of Eigcn-Vectors

For any flying vehicles (missiles or aircrafts), the mathematical models are basically nonlinear differential equations. Although linearized models have been used successfully for analysis and design, the nonlinear characteristics are still very important and need to do some basic and detail analysis. The regions of asymptotic stability is one of the nonlinear characteristics which must be analyzed carefully.
