This study addresses the antivibration issue of a full aircraft active landing gear system(LGS)under landing impact and runway excitations via a novel adaptive observer-based integral event-triggered control method.First,a full aircraft active LGS comprising a front gear and two synchronized main left and right gears with active suspensions is established,where the information exchange among them is not implemented directly.Second,two adaptive observers are designed separately for the front and main LGSs to identify the varying damping parameters and estimate the system states simultaneously.Third,estimated states are transmitted to a shared network through a novel integral event-triggered mechanism(I-ETM);thus,the front and main LGSs are interconnected,and a networked control scheme for the aircraft LGS is constructed.Additionally,the integrated active control law is designed with the aid of the transmitted states of the front and main LGSs,enhancing the robustness against the pitch vibration of the aircraft.Furthermore,the L2-stability of the hybrid system is guaranteed to depress the vertical vibration effect of the landing impact and irregular runway excitations,thus improving passenger safety and comfort.Moreover,a codesign method is provided to obtain feasible solutions to the gain matrices of the observers and controllers simultaneously.Simulation and comparison results are presented to illustrate the effectiveness and superiority of the proposed control scheme in antivibration and saving communication resources.
