Abstract： Sensors，controllers，and actuators are connected by network control systems（NCSs） through communication networks，which is facilitating remote monitoring and inteligent control and offering the advantage of transcending geographical constraints. However，a multitude of problems arise from its open nature and network dependency. Firstly，the problems existing in networked control systems，such as signal quantization errors，packet loss， network-induced delays， bandwidth occupation，and network security threats are systematically analyzed in this paper. Subsequently，based on a review of research achievements in networked control systems，the new control strategies including novel quantization control，stochastic packet-loss control，self-triggered control for time-varying delays，variable sampling period intelligent scheduling control，dynamic event-triggered control，and networked control under DoS（denial of service）attacks are proposed. Then，relevant control theoretical methods such as stochastic system methods，predictive control methods，delay estimation and compensation，fuzzy feedback methods，and neural network predictive methods are summarized. Finally，the challnges faced by networked control system research in the future are presented.
