Abstract :
This paper is concerned with the operator-based nonlinear networked control systems with packet errors. In communication network, packet may include errors caused by noise in network, and in conventional control method, these packets are regarded as lost packets. This means information of control signals is also lost completly, even if the disturbance caused by errors is acceptable for control systems. The proposed system treats packets in communication networks with errors as control signals with perturbation. This control scheme reduce the numbers of dropped packets caused by noise in communication network. Firstly, the operator-based plant model and packet communication model with packet error is proposed. Secondly, the operator-based nonlinear control system is proposed. Finally, the effectiveness of the proposed control scheme is confirmed by simulation.
