| 英文摘要 |
| This paper proposes a novel event-triggered tracking control scheme for a class of strict-feedback nonlinear
systems based on deterministic learning. Firstly, this paper designs an adaptive neural network control for strict-feedback
systems on the local control test side and realizes the knowledge acquirement of unknown dynamics in the control process.
Then, based on stored constant weights, this paper designs a novel event-triggered controller and a triggering condition. By
combining Lyapunov stability analysis with nonlinear impulse dynamic system theory, the proposed control scheme can
be verified to guarantee that the tracking error converges to a small neighborhood of zero and all the signals in the closedloop
system are uniformly ultimately bounded. Moreover, the proposed control scheme uses constant weights instead
of estimated weights, which makes the proposed scheme possess some good features including the easy-to-implement
triggered condition, the improved transient control performance, and the less network resource occupancy. A comparative
simulation is given to illustrate the effectiveness of the proposed scheme. |
