Abstract
Several issues in Networked Control Systems (NCSs) such as networked delay, sampling, transmitting methods and datadropout make the system response goes unstable. This paper deals with networked delay problem and proposes AdaptiveRetuning PID Controller to overcome effect of time delay change by adaptively changing its two parameters, Ti and Td . Theresults show that, with delay 0.03 - 0.07 second, where these are bigger than nominal delay of networked system (<1ms), theproposed controller can enhance the system response as close as its original designed controller.Downloads
