Abstract
In this paper, the observer-based predictive control problem for networked control systems (NCSs) subject to the time-delay is investigated based on the event-triggered strategy. Initially, the output-based event-triggered mechanism is introduced in order to reduce the transmission times effectively in the capacity-limited communication network. Then, the system states are reconstructed from the output measurements by utilizing a popular Luenberger observer. Next, the model-based networked predictive control (NPC) scheme is developed to actively compensate for the communication delay. Moreover, based on analysis of the augmented system, sufficient conditions that guarantee the asymptotic stability of the system are obtained. Finally, a simulation example is given to demonstrate the effectiveness in the reduction of network utilization and compensation for communication delay of the proposed controller design method in NCSs.
