【Abstract】 The complex dynamics characters of the Josephson junction circuit system are studied and the tunnel effect is considered.The dynamical equation of the system is established.By phase plane portraits and bifurcation diagram,the route from periodic motion to chaos is studied under the presented system parameters.The method of chaos control based on the linear and nonlinear transformation of system variables is constructed to control the chaos of the Josephson junction circuit system.The phase plane portraits and bifurcation diagram are obtained.The stable dynamical behavior orbits can be obtained when changing the linear transformation matrix of system variables.更多还原
