摘要：
For a class of nonlinear cyber physical systems with time-varying communication constraints, the networked predictive control strategy is adopted in this paper. It does not use the conventional passive suppression method but employs the active compensation method to overcome the time-varying communication delay and data loss. To make the method of compensating for time-varying communication constraints simple, active and universal, a novel networked nonlinear predictive control method is proposed. The designed networked nonlinear predictive controller can achieve the same expected control performance as a local closed-loop control system without networks. At the same time, the necessary and sufficient conditions for the stability of the closed-loop networked nonlinear predictive control systems are derived. Numerical examples show that the proposed networked nonlinear predictive control method can fully compensate for the time-varying communication delays in cyber physical systems. © 2022, Editorial Department of Control Theory & Applications South China University of Technology.
