摘　　要：控制回路通过实时网络闭环而成的反馈控制系统称为网络控制系统。文中介绍了时间驱动和事件驱动的异同,建立了节点在不同驱动方式下网络控制系统的数学模型。由分析可知在设计网络控制系统时要对传感器、控制器、执行器选择合适的触发方式。NCS （Networked Control System） is a kind of feedback control systems where the control loops are closed through real-time control network, Similarities and differences between time-driven and event-driven were introduced in this paper, and the models of the networked control system with different driven modes to the nodes were given. In the design of networked control system suitable trigger modes to the sensor, the controller, and the actuator should be chosen.

关 键 词：网络控制系统 时间驱动 事件驱动 时延
