Control of Internet based robotic teleoperation via hybrid dynamic system approach

Abstract

During the control of teleoperation via Internet, an operator cannot obtain the real-time data in a timely and accurate fashion. This is due to the uncertain time delays, which are unavoidable in the Internet-based communication and cause instability and poor system performance. This paper deals with the modelling and control of Internet-based teleoperation systems using the hybrid dynamic system approach. A supervisory controller is implemented to overcome the uncertain time delays. This method provides an efficient way to model the concurrence and complexity of the Internet-based robotic teleoperation. © 2004 IEEE.
