Abstract :
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.
