摘　　要：This paper presents a new smooth memristor oscillator, which is derived from Chua＇s oscillator by replacing Chua＇s diode with a flux-controlled memristor and a negative conductance. Novel parameters and initial conditions are dependent upon dynamical behaviours such as transient chaos and stable chaos with an intermittence period and are found in the smooth memristor oscillator. By using dynamical analysis approaches including time series, phase portraits and bifurcation diagrams, the dynamical behaviours of the proposed memristor oscillator are effectively investigated in this paper.This paper presents a new smooth memristor oscillator, which is derived from Chua＇s oscillator by replacing Chua＇s diode with a flux-controlled memristor and a negative conductance.
