| 英文摘要 |
| In this work, we present a dual-periodic repetitive control scheme that deals with periodic tracking tasks for
a class of nonparametric uncertain systems, with no common multiple between the period of the disturbance and that of
the reference signal. The learning controller is designed based on the Lyapunov synthesis, compensating nonparametric
uncertainties and the periodic disturbance by both robust mechanism and dual-period repetitive learning mechanism. The
unlimited learning strategy is applied to estimate time-varying parameters. Through rigorous analysis, we prove that the estimations themselves are bounded, indicating an improvement on the mere boundedness of L2-meaning from most existing
works. As the repetitive cycle increases, the system output can track its reference signal perfectly over its full period. In the
end, an illustrative example is provided to demonstrate the efficacy of the proposed dual-period repetitive control scheme. |
