Design and application of a servo control system based on a fuzzy active Disturbance Rejection Controller

Aim. The introduction of the full paper reviews Refs.1 through 6 and points out that there is an urgent need to explore the performance of a Fuzzy Active Disturbance Rejection Controller (Fuzzy-ADRC). Sections 1 and 2 explain the results of our exploration. Their core consists of: the Fuzzy-ADRC control system based on the rudder control system was designed. The Fuzzy-ADRC is composed of three parts: a tracking-differentiator, an extended state observer and a fuzzy nonlinear state error feedback control law. The simulation results, given in Figs. 5, 6, 7, 8, 9, and 10 and their analysis show that the Fuzzy-ADRC system has the characteristics of simple structure, better robustness and better dynamic/static characteristics than the conventional PID and ADRC controller under all operating conditions.
