Abstract

When a Networked Control System (NCS) operates over the communication network, one of the major challenges is the network-induced delay in data transfer among the controllers, actuators, and sensors. This delay may degrade system performance and even cause an unstable system. This paper proposes an adaptive Generalized Predictive Control (GPC) with the Kalman state estimator to cope with network-induced delay. The adaptive GPC is implemented in Wireless NCS (WiNCS) based on IEEE 802.11b, using the PiccSIM platform and Network Simulator version 2 (NS2) for simulation and analysis.
