摘要：
The bandwidth method is the most commonly used parameters tuning method for linear active disturbance rejection controller (LADRC). However, the controller is of high order and it is difficult to select the relative gain while applied to complicated processes. Thus, this paper proposes a frequency domain approximate tuning method based on the controller with known plant information. The controller is designed via general active disturbance rejection control (GADRC), and then parameters of second-order LADRC can be achieved by approximation with GADRC in frequency domain. Combing the advantages of both LADRC and GADRC or other controllers, it can be expected to attain desired performance with convenience. © 2019, Editorial Department of Control Theory & Applications South China University of Technology.
