Global stability in hopfield neural networks with distributed time delays

In this paper, without assuming the boundedness, monotonicity and differentiability of the activation functions, the conditions ensuring existence, uniqueness, and global asymptotical stability of the equilibrium point of Hopfield neural network models with distributed time delays are studied. Using M-matrix theory and constructing proper Liapunov functionals, the sufficient conditions for global asymptotic stability are obtained.

The research on robust control design railway of vehicle active suspension

This paper presents a systematic approach for the robust performance design of active suspension system. The robust control of vehicle active suspension is studied deeply by using the modern robust control synthesis approach-/spl mu/ approach. With the digital controller designed, the hybrid computer simulation of the robust active suspension system is carried out and simulation results are given.
