For suspension control of low-speed PEMS train, the usual strategy is to separate the maglev module into two individual single points, which neglects the coupling effect of adjacent single point. To suppress the coupling effect, this paper suggests the method of designing control law considering the whole module. The simulation result verifies the validity of the new control law, which can suppress...
Currently, computer is widely used in a ground vehicle or at the aircraft. However, the vibration maybe impact on the computer, especially the HD array. Therefore, this paper presents a new mechanical and electromagnetic composite vibration isolation system, adding active electromagnetic vibration isolation devices on the foundation of passive mechanical vibration isolation system. Symmetric electromagnets...
In this paper, a new algorithm is proposed to compute the special positive definite solution which is the unique solution of a special matrix equation. The new algorithm outperforms the existing algorithms for solving the matrix equation in computational costs.
Time delay is a kind of common nonlinearity, which is consisted in many parts of suspension system of high speed maglev train.In this paper, the dynamic behavior of suspension system of maglev train with time-delayed velocity and acceleration feedback signal is considered with rigid guideway. Taking time delay as its bifurcation parameter, the condition with which the Hopf bifurcation may occur is...
