Abstract :

Modern control systems widely use network to decrease the implementation cost and also increase the performance. Although they have several advantages, they suffer from some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally can lead to system instability. To prevent such problems it is important to model the system properly. In this paper, a new function has been proposed for error modeling. Moreover, different influences of system parameters and packet loss on error function have been investigated and it has been determined that changes of which parameter has more contribution on packet effect in error function. Considering these parameters is very critical in designing systems.
