【Abstract】 A kind of magnetic bearing system with time delay is considered. Linear stability of the model is investigated by analyzing the distribution of the roots of the associated characteristic equation the exultance of stability and periodic solutions of system with the different parameter is discussed by the analysis results, it is found that the Hopf bifurcation occurs when the delay passes through a sequence of critical Values.更多还原
