Abstract
The observing capability of the Active Disturbance Rejection Control (ADRC) for the general systems is discussed in this study. The frequency performance of the Linear Extended State Observer (LESO) is analyzed. And the theoretical result is verified by simulations. It is shown that ESO can estimate the required states at the designed speed, in spite of the different total uncertainties.
