Internal Stability of Second-order Linear Active Disturbance Rejection Control System
The relationship between total disturbance and stability is an important issue of active disturbance rejection control. Focusing on the simple and typical case that the plant is a second-order linear time-invariant and the external disturbance is additive, this paper investigated the stability of se...

| Summary: | The relationship between total disturbance and stability is an important issue of active disturbance rejection control. Focusing on the simple and typical case that the plant is a second-order linear time-invariant and the external disturbance is additive, this paper investigated the stability of second-order linear active disturbance rejection control. It chooses internal stability as the stability definition, and finds a sufficient and necessary stability condition. The condition is related to the uncertain parameters of the plant, but is independent of external disturbances and does not require internal disturbances to be bounded. Thus, the bounded total disturbance assumption which is often used in existing literature can be removed. |
