Frequency Response Analysis of Linear Active Disturbance Rejection Control
In this paper, the design of linear active disturbance rejection control (LADRC) for high order systems is presented and the frequency response is analyzed. First, the LADRC for minimum-phase processes is introduced, and the parameterization of tuning paramters, which reduces the tuning parameters t...
