Is ADRC robust control or adaptive control?

Active disturbance rejection control is a kind of robust or adaptive control.

Adaptive control can be regarded as a feedback control system, which can intelligently adjust its own characteristics according to the change of environment and make the system work in the optimal state according to some set standards. Generally speaking, adaptive control is very successful in the control of aviation, missiles and spacecraft. It can be concluded that the traditional adaptive control is suitable.

Advantages of ADRC:

Modeling, uncertainty, external interference, measurement noise and other practical factors. In the design of control system, we should know how PID and other different controllers deal with these non-ideal factors. Only in this way can we make a relatively objective evaluation of the proposal, development, application, advantages and disadvantages of ADRC from different aspects.
