N2 - Aiming at the situation that the typical stiffened panel structure in aeronautical engineering will be impacted by shelling vibration, resulting in the failure of the structure and equipment vibration, the fractional order PID (FOPID) controller is used to control the transient impact response, which accelerates the attenuation of the structural response speed. Taking the stiffened panel with the macro fiber piezoelectric composite (MFC) piezoelectric sheet as the controlled object, the particle swarm algorithm is used to optimize the controller parameters, and the RMS reduction ratio of the random response of the system model and the reduction of the PSD spectrum peak is reduced. As the objective function of the controller, a corresponding fractional-order PID controller is designed. The crank-link mechanism is used for transient excitation, and the results show that fractional-order PID can effectively improve the decay rate of the transient excitation response of the stiffened wall plate structure, and the logarithmic decay rate of the transient excitation response of the structure is increased by at least 142%. The controller has good application potential for active control of the transient excitation response of stiffened panel structures.
