Abstract: A novel chaotic system with multi-wing attractors was proposed based on the conjugate Lorenztype system and by introducing flux-controlled memristor． Single-wing，two-wing，three-wing and four-wing chaotic attractors can be produced by changing the system parameters． The dynamic characteristics of the system were analyzed through phase diagrams，Lyapunov exponents，bifurcation diagram，etc． An analog circuit of the system was designed and simulated by Multisim． The circuit simulation results were consistent with the results of numerical analysis，which verifies the system's chaotic behaviors and shows its implementability． Finally，an adaptive sliding mode synchronous controller was designed based on the Lyapunov stability theory，and the given signal was tracked within 0. 25s and the position parameters was identified quickly within 0. 12s by the controller． 

Key words: flux-controlled memristor, chaotic system, sliding mode, adaptive synchronization control
