We numerically study the synchronization of two unidirectionally coupled single-mode semiconductor lasers in a master-slave configuration. The master laser is an external-cavity laser that operates in a chaotic regime while for the slave laser we consider two configurations. In the first one, the slave laser is also an external-cavity laser, subjected to, its own optical feedback and the optica...

This paper studies the effects of three methods of kinematic redundancy resolution on teleoperation performance with a redundant slave robot in telemanipulation. First, we derived three kinematic redundancy control modes expressing different trade-offs between kinetic energy level, joint usage, and joint limit avoiding. To validate our algorithms we performed simulations, autonomous robot tests...

In order to solve the problem in master-slave heterogeneous teleoperation systems, which is that inverse solution of robot cannot be achieved when mapped wrist joint exceeds reachable space joint, a mapping method based on link pose constraint proposed. The means position and orientation hand are same or similar exoskeleton link. proposed method, used an exoskeleton-based system realize consist...

This paper is concerned with an application of the use of extra freedom in the coordinates transformation for exact linearizaion. We apply this technique to obstacle avoidance of a manipulator in the master-slave control. We show how to use the freedom for such an object and give the way to construct the linearizing coordinates transformation and feedback. Furthermore we evaluate the e ectivene...

In this letter, adaptive synchronization of two uncertain chaotic systems is presented using adaptive backstepping with tuning functions. The master system is any smooth, bounded, linear-in-the-parameters nonlinear chaotic system, while the slave system is a nonlinear chaotic system in the strict-feedback form. Both master and slave systems are with key parameters unknown. Global stability and ...

This paper describes the election algorithm that guarantees the reliability of TEMPO, a distributed clock synchronizer running on Berkeley UNIX 7 4.3BSD systems. TEMPO is a distributed program based on a master-slave scheme that is comprised of time daemon processes running on individual machines. The election algorithm chooses a new master from among the slaves after the crash of the machine o...
