摘      要：Dear editor,This study reports the discovery of active disturbance rejection control (ADRC).Second-order linear ADRC (LADRC),the basic and most popular ADRC,can be interpreted as a modified proportional-integral-derivative (PID) control.LADRC filters the PID feedback compensator with a second-order low-pass filter;it also adds a pre-filter.Simultaneously,each given PID con-
