| 英文摘要 |
| In this paper, the iterative learning robust control problem, described by a two-dimensional (2??D) model, for
uncertain discrete systems with event triggering mechanism is studied. Firstly, to reduce the update times of control signals
in the iteration process, an event triggering mechanism along the iteration axis is constructed, and an iterative learning
control algorithm based on the event triggering mechanism is proposed. Based on the 2??D system theory, the iterative
learning process is transformed into the equivalent 2??D Roesser system. Then the Lyapunov function is constructed,
combined with the linear matrix inequality (LMI) technique, the sufficient conditions for the asymptotic stability of the
system are given, and the controller gain matrix is further obtained. Simulation results further verify the effectiveness of
the proposed event triggering mechanism. |
