Prove 0 is an exponentially stable equilibrium of the system x = f ( x ) + g ( x ) if f ( 0 ) = g ( 0 ) = 0
Besides the conditions in the title, we have:
1. 0 is an exponential equilibrium of the system y = f ( y )
2. | g ( x ) | μ | x | , x R n
3. μ is sufficiently small!
What I have tried so far is that:
1. | | y ( 0 ) | | < δ 1 | | y ( t ) | | < α 1 | | y ( 0 ) | | e β 1 t , t 0
2. We want to prove: δ , α , β > 0 , such that
| | x ( 0 ) | | < δ | | x ( t ) | | < α | | x ( 0 ) | | e β t , t 0
Considering the following system:
1. x 1 ( t ) = f ( x 1 )
2. x 2 ( t ) = g ( x 2 )
Then we will have:
1. α 1 , β 1 , δ > 0 such that
| | x 1 ( 0 ) | | < δ 1 | | x 1 ( t ) | | < α 1 | | x 1 ( 0 ) | | e β 1 t , t 0
2. x 2 ( t ) μ | x 2 ( t ) |, and by Gronwall inequality x 2 ( t ) x 2 ( 0 ) e μ t
I have a sense that it might be somewhat close to what we want to get. And I am stuck at this stage.
