Abstract: A fuzzy linear/nonlinear active disturbance rejection switching controller is proposed to deal with the strong nonlin-ear interference and the influence of model uncertainty encountered by the jamming bomb in the combat process. Firstly, mathematical models with the flywheel angular velocity as the controlled variable and the rolling angle as the controlled variable are established for the roll motion simulation device of the jamming projectile. The fuzzy rules are used to improve the linear/nonlinear active disturbance rejection switching control conditions, so as to achieve more stable fuzzy soft switching. Then, the strategies of the closed inner loop of Active Disturbance Rejection Control (ADRC) of flywheel angular velocity and the closed outer loop of fuzzy linear/nonlinear active disturb-ance rejection switching control of roll angle are used. Finally, the simulation model and experimental platform of the system are built. The simulation and experimental results show that the controller has the advantages of linear and nonlinear ADRC, and has high applicability.
