Abstract In order to solve the contradiction between system fast response and small overshoot, and to further improve the control performance of control system, the secondorder fuzzy immune active disturbance rejection control (ADRC) strategy was proposed combined with immune control theory and ADRC technology. The robustness of the control system was improved by bioadaptive immune mechanisms, and the contradiction between small overshoot and short rise time was resolved to some extent. Speed and tension were strongly decoupled by the secondorder ADRC technology. Nonlinear intelligent immune control was achieved by fuzzy algorithm. The stability of control system was proved. The results of simulations and experiments show that the control strategy is superior to the traditional PID control. The twoorder fuzzy immune ADRC has rapid response speed, strong decoupling ability, high tracking accuracy and strong antiinterference ability.
