The chaotic behaviours of a fractional-order generalized Lorenz system and its synchronization are studied in this paper.A new electronic circuit unit to realize fractional-order operator is proposed.According to the circuit unit,an electronic circuit is designed to realize a 3.8-order generalized Lorenz chaotic system.Furthermore,synchronization between two fractional-order systems is achieved by utilizing a single-variable feedback method.Circuit experiment simulation results verify the effectiveness of the proposed scheme.
