Abstract:
The observers are used to estimate some variables of one system, they improve the sensors because the sensors obtain the measures with noise, while the observers obtain the measures without noise. Furthermore, the observers are less expensive than the sensors. In this paper, two novel observers are compared for the estimation of states. Exponential stability of both observers is assured. The proposed methods are verified by two examples.
