Discrete-Time Output-Feedback Robust Repetitive Control for a Class of Nonlinear Systems by Additive State Decomposition

摘要: The discrete-time robust repetitive control (RC, or controller, also designated RC) problem for nonlinear systems is both challenging and practical. This paper proposes a output-feedback RC design class of subject to measurable nonlinearities track reference robustly with respect the period variation. relies on additive state decomposition, by which decomposed into an linear time-invariant system state-feedback stabilization system. Thanks existing controller methods in frequency domain time can be employed make robustness discretization tractable. To demonstrate effectiveness, illustrative example given.
