This paper studies the tracking control problem of nonlinear networked and quantized control systems. The desired trajectory is generated by the reference system. Due to the reference system and the network, the errors induced by the network are not attenuated and affect the convergence of the tracking error. Therefore, a unified hybrid model is developed. Using Lyapunov theory, sufficient conditions are derived to guarantee the convergence of the tracking error, which depends on the network-induced errors. In addition, the existence of the Lyapunov function is studied. Finally, a numerical example is used to illustrate the obtained results.
