网络控制中基于FSMC观测器的时延补偿

针对网络控制系统中因存在通讯时延、网络诱导噪声及数据丢失等而可能引起系统性能降低或不稳定的问题，利用模糊滑模控制理论，在时延存在的情况下，基于观测器建立不确定网络控制系统模型；并利用预估方法对网络控制系统的时延进行补偿，从而保证系统的稳定。设计模糊滑模控制器（FSMC）来抑制网络控制系统中的诱导噪声及滑模面上的“抖动”，以及采用预估补偿策略处理网络中的时滞和数据包丢失等，可有效保证系统的稳定。仿真实例表明了该算法的合理性、有效性。

Time Delay Compensation for Networked Control Systems Based on FSMC Observer

The fuzzy sliding mode control(FSMC) method is applied to guarantee the stability of networked control systems in view of the common existing problem of communication delays,networked-induced noise and data packet dropout.The uncertainties of networked control systems with time delay are adopted based on the observer.The FSMC is used to deal with the networked-induced noise and the chatters,and predictive way is used to deal with time delay and data packet dropout.And then the stability condition of networked control systems is guaranteed.Simulation results show that the proposed theory is reasonable and effective.
