Abstract：The effect of ADRC on the control of long time?鄄delay and strong interference system is poor. The key reason is the mechanism of static parameters. Aiming at its three main parameters related to interference rejection，an improved PSO algorithm?鄄based on?鄄line optimization method is proposed. In order to raise the efficiency of dynamic optimization，two improvements are applied in the PSO algorithm. The first one is using error threshold to trigger PSO as servo mechanism. The other is using the Pareto elitism strategy in the PSO algorithm. Simulation results show that the proposed PSO?鄄based dynamic ADRC has strong robustness and adaptability for the systems with long time?鄄delay and strong interference.
