It is well known that providing a human operator with contact force information can significantly improve task performance in a teleoperation system. Unfortunately, time delay is a serious problem for such systems. Even a small time delay in a bilateral teleoperation system will generally degrade the system's performance and cause instability. Consequently, without some form of compensation for time...
A Web-based remote control system of a mobile manipulator over Internet is studied. Due to the development of Internet technique and speed increase of transmission, the inexpensive convenient communication approach is provided for the remote control system. However, time delay on Internet is considered as a problem which affects the stability of teleoperation system. Therefore, based on the test and...
Due to the bandwidth constraint, the network inevitably induces time delay in the Internet-based control system, which will affect the performance of Internet-based closed-loop control systems such as performance degradation and system destabilization. The variable-rate sampling strategy is proposed based on the proposed dual closed-loops control architecture to overcome the uncertain transmission...
