Abstract :
In this paper, the design method of decentralized controllers using 3-order active-disturbance-rejection-control (3-ADRC) is presented. 3-ADRC can compensate the non-modeled dynamics and external disturbances of the system by using 3-order extend state observer, and decouple among loops. A set of parameters is obtained by optimum algorithm. By introducing a significant reduction to the control parameters, the decentralized 3-ADRC controller is easy to be tuned. The proposed method is applied to seven examples from literature. Simulation results show that the decentralized 3-ADRC is feasible and better than referenced methods in the control of complicated multi-loop systems.
