Abstract

With the merit of simple algorithm, strong robustness and anti-interference capability the ADRC not relying on the accurate math mode of controlled plant has caught the attention of control experts and scholars; but the parameter self-tuning of ADRC isnpsilat as easy as PID controller, because there are more parameters to be turned. An expert ADRC is designed in this paper. Uncertain plant is controlled by carrying out the most suitable control strategy of ADRC obtained by specialist system. The simulation demonstrates that the controller has strong anti-interference capability, strong adaptability and good control effectiveness especially for the plants with large delay and large inertia.
