Abstract

ABSTRACT

NCS is the combination of control system with control loops that used to regulate feedback signals among system. With the promising research vogue in academic and industry domains stimulate the emergence and advancement of networked control system. In nonlinear systems one of the foremost altercates is communication delays and packet losses. In this paper we analyzed different network control schemes, data rates and other network parameters to investigate the performance of our control system in a comprehensive way. It is also demonstrated by simulations and practical experiments that the several network control systems can compensate for arbitrary communication data dropout to attain anticipated performance and loop stability. The results demonstrate that as the data rate increases, frame size becomes lower and path loss exponent is decreased. Moreover, the control system response can be improved by increasing transmit power and error coding threshold.
