摘要 传感器、控制器与执行器的数据经网络进行传输与交换的闭环控制系统称为网络控制系 统。网络控制系统是随着计算、通信和控制发展起来的新一代控制系统。目前针对网络控制系统的 研究已愈来愈受到业内人士的关注,但是大都是通过软件模拟的方法。网络控制系统作为应用型的 领域,软件模拟忽略了实际中的不确定性,因此有局限性。本文介绍基于CAN总线的网络控制系 统仿真平台,包括硬件和软件,在现实的网络环境下解决网络控制系统中的种种问题。同时通过一 个在此仿真平台所做的实例,以证明网络引起的时延会引起控制系统的不稳定。 Networked control systems (NCS) are a kind of closed-loop control systems where the sensors, the controller and the actuators exchange data through network. NCS is a kind of new control architecture developing with computing, communication and control. More and more work has been done on NCS. For improving research to meet with the realistic condition we design a simulation platform based on CAN, and a simulation instance is presented, which proves that the delays induced by network will cause instability of the control systems.
