【Abstract】 By taking different values of the fractional-orders q（q₁= 0.9,q₂= 0.9,q₃= 0.8）,the dynamic properties of the three-dimensional heterogeneous fractional order chen system are investigated via phase diagram,bifurcation and Poincaré diagrams.The tree type,chain type and mixed type plural analog circuit are designed using Multisim electronics platform to implement the new system.The plural circuit experimental results are all consistent with Matlab numerical simulation results,which show the effectiveness of the proposed circuit and prove that chaos actually exits in the heterogeneous fractional order chen system.更多还原
