A procedure for designing a feedback control to asymptotically stabilize a quasi-nonintegrable Hamiltonian system with Markovian jump is proposed.First,the Markovian jump averaged stochastic different
The stochastic bifurcation of a rotor system with coupling faults is investigated.Firstly,the dynamical model of the rotor system with random uncertainty is established,where the faults coupled with t
The synchronization problem of coupled neural networks via impulsive control is investigated in this paper.Based on a time varying Lyapunov functional associated with the impulsive instants,the delay-
Bolted structures in composite structures play the role of connecting and transferring loads between substructures.Once uncertainties of bolted structures are taken into consideration,the dynamic anal
As the number of cars increases,the problem of traffic congestion has become increasingly prominent.The stability of the car-following model means that the car can maintain a speed and headway in the
The mainly measurement of the position and size of making hole of the iron tower member is template comparison,which is difficult to adapt to the automation production.Firstly,for the workpiece to be
