An IQC formulation of stability analysis for bilateral teleoperation systems with time delays

I Polat - 2011 IEEE World Haptics Conference, 2011 - ieeexplore.ieee.org
Many teleoperation applications exhibit significant communication delays between operator
commands and the resulting actions at the remote site. In this paper we present the stability …
