“…In industrial networking (including wireless smart devices embedded in wireless RF chips), the present paper hope to further improve the performance of clock synchronization enhancing DMPC when considering papers [27] on Robust and stochastic MPC. The on-line synthesis approaches of MPC have been investigated for NCS (Networked Control Systems) where the packet loss and data quantization are coexisting (see [25]) and network-induced delays (see [26]), and is the one which guarantees the closed-loop stability, i.e. the closed-loop system is stable whenever the optimization problem is feasible.…”

In the industrial cyber-physical environment, the performance of clock synchronization with loss of data packets should be analyzed quantitatively. The localized state estimator and controller are designed to realize the speed of convergence for exponential stability of the clock synchronization for the output feedback tubes-model predictive control (Tubes-MPC) of the state-space model. The upper and lower bounds for the variance of synchronization error under the statistical significance were quantitatively analyzed in incomplete measurement. The set of interference error in complete measurement was added into the set of additional estimated errors introduced by packet loss. Clock synchronization of the output feedback Tubes-MPC which has been constructed still has the performance of robust exponential convergence under networked packet loss, and it can be extended to an absolute state-space model with network-level in a unified approach.

“…Based on that, particularly, some researchers have adopted MPC methods to generate optimal inputs to predict the future dynamic behavior of linear time-invariant NCSs. [6][7][8] Wu et al 9 proposed an MPC method for NCSs while considering the bounded and random networked communication delays. In Reference 10, not only the random delay but the packet disordering was contained in the studied NCSs, and an MPC strategy was designed to make the closed-loop NCSs stochastically stable.…”

This article develops a novel event‐triggered subspace predictive control (ET‐SPC) method for discrete‐time linear parameter‐varying (LPV) systems with partially unknown system parameters. An event‐triggered law is developed to alleviate the heavy load of data transmission and computation in the conventional subspace predictive control methods for the LPV systems. The design of the event‐triggered law relies on the input‐to‐state stability (ISS) theory and applies the robust stability condition based on linear matrix inequalities (LMIs), which guarantees the stability of the proposed method. Consequently, the input component can be directly transmitted to the system without receding horizon optimization when the event‐triggered law evaluates that the system satisfies the stability condition. The simulation results illustrate its satisfactory performance, which indicates its potential application involving a considerable amount of data transmission and computation such as the network control systems (NCSs).

“…In the context of an unreliable networked environment, the problem of time delays generally cannot be avoided because of distributive nature, which may potentially affect the performance and stability of the RHC for network control systems (NCSs) [16][17][18]. In [19], an off-line synthesis approach is investigated, and a new augmented model is proposed to describe the NCS subject to bounded deterministic network-induced delays. In [20], the robust fuzzy MPC is presented for time-delay systems.…”
