In this paper, based on passivity theory, coexistence of anti-synchronization and complete synchronization is found between two identical hyperchaotic Lü systems with different initial conditions. The passive controller is employed to make the error dynamical system not only passive but also asymptotically stable. Numerical simulation results illustrate that the designed controller can realize anti-synchronization of three pairs of states and complete synchronization of the remaining one pair.

In this paper, a new four-dimensional continuous-time autonomous hyper chaotic system, which has a complicated four-wing attractor, is formulated by adding a linear controller to a chaotic system. The existence of the hyper chaos is verified with bifurcation analysis and Lyapunov exponent spectrum. The bifurcation routes from periodic, chaotic to hyper chaotic evolutions are observed simultaneously. The essential dynamical behaviors are demonstrated not only by numerical simulation but also by circuit realization.

In this paper, the grasp operation of an underactuated finger mechanism is simulated with the aim to characterize and analyze its performance. The design of the proposed mechanism is based on spring systems that give suitable underactuation characteristics. A CAD model is proposed and then it is used in a procedure for numerical simulation. Simulation results show suitable capability for grasping a wide range of objects in size and shape by operating the mechanism inside the finger body. The achieved grasp has been simulated as a human-like functionality with a grasp contact in each phalanx.
