Abstract :
An off-line optimization, on-line execution robust model predictive control algorithm (RMPC) is designed for networked control systems (NCSs) with long time varying delays in feedback channels. Invariant sets are predetermined via off-line optimization, and on-line controller gains are selected according to system states. Predicted values are used to compensate data dropouts. Simulations and comparisons show effectiveness of the designed controller.
