| 摘 要： | The unified chaotic system contains the Lorenz and the Chen systems as two dual systems at the two extremes of its parameter spectrum and the Lu system as a special case.The parameter identification and tracking problem of the unified system are further investigated.In particular,a novel controller is designed for avoiding the divergence of the factor 1/x.Numerical simulations are provided to show the effectiveness of these methods.
