英文摘要 |
This paper proposes an event-triggered dual-mode distributed model predictive control method for large-scale
linear discrete-time systems subject to bounded disturbances. The event-triggering condition, which involves information
of the subsystem itself, is obtained by the input-to-state stability (ISS) theory. Only when the event-triggering condition
is satisfied, the state measurement is sent and the distributed model predictive control optimization problem is solved.
Meanwhile, the subsystem exchanges its optimal state trajectories with neighbor subsystems. When the subsystem enters
the invariant set, the state feedback control law will be applied. Moreover, no information will be exchanged between the
subsystem and its neighbor subsystems which also enter the invariant sets. The upper bound of disturbances are derived by
analyzing the recursive feasibility and closed-loop stability. Finally, the algorithm is verified through the vehicle control
systems. Simulation results show that the presented method is able to reduce the solving frequency of optimization problems
and the number of information transmissions, thus saving the computation resources and communication resources. |
