  An H infinity adaptive fuzzy control design is proposed in this paper for
unknown nonlinear networked systems. The main issues of networked systems are
addressed here, which are the system delay and loss of information. In fact,
the proposed method overcomes the delays by filtering the errors and also
compensates the loss of system information. The adaptive fuzzy control design
is combined in this work with H infinity control approach to approximate the
system's unknown nonlinear functions. The stability analysis of the approach is
also surveyed. The results revealed that the closed loop system stability is
proved in existence of system disturbances, system delays and information loss.
The proposed approach is applied on an inverted pendulum system to evaluate the
method's efficiency and effectiveness.
