摘要

网络引起的长时延不仅是不可避免的，而且通常是不可预测的和随机的，它会降低不考虑时延的控制系统的性能，甚至使系统不稳定。提出了一种基于系统状态预测向量的滑模控制器(SMC)，用于系统的时滞补偿。通过对滑模控制方案的预测，及时补偿了系统的长时延。仿真结果表明了该补偿方法的有效性。

Time delay compensation for networked control systems based on SMC

The network-induced long delays are not only inevitable, but also usually unpredictable and stochastic, which degrade the performance of control systems designed without considering time delays and even destabilize the systems. A new sliding mode controller (SMC) based on the predicted vectors of the system states is proposed for time delay compensation. By the prediction of the sliding mode control scheme, the long time delays are compensated in time. Simulation results show the effectiveness of this compensation method.
