摘要

As the core of all other ADRC variants covered in this book, the linear continuous-time state-space form of active disturbance rejection control is introduced in this chapter. Generalizing the first- and second-order cases considered in Chap. 2 , the structure of Nth-order linear ADRC is being discussed, consisting of observer and state-feedback controller. Equations for tuning both observer and controller are derived for the so-called bandwidth parameterization approach.
