چکیده
This study addressed sufficient conditions for the robust monotonic convergence of repetitive discrete-time linear parameter varying systems, with variation rate bound. The learning law under consideration is an anticipatory iterative control. Of particular interest in this that iterations can eliminate influence disturbances. Based on a simple quadratic performance function, condition proposed algorithm presented terms matrix inequality (LMI) by imposing polytopic structure Lyapunov matrix. set LMIs to be determined considers bounds scheduling parameter. control designs polynomial ILC constructing sequence inputs R-LPV system, producing dynamic system respect uncertain parameters. Numerical simulations were performed demonstrate benefits technique.

Iterative Learning Control for uncertain systems: Robust monotonic convergence analysis
In this paper, we present a novel Robust Monotonic Convergence (RMC) analysis approach for finite time interval Iterative Learning Control (ILC) for uncertain systems. For that purpose, a finite time interval model for uncertain systems is introduced. This model is subsequently used in an RMC analysis based on μ analysis. As a result, we can handle additive andmultiplicative uncertainty models ...
متن کاملIterative learning identification and control for dynamic systems described by NARMAX model
A new iterative learning controller is proposed for a general unknown discrete time-varying nonlinear non-affine system represented by NARMAX (Nonlinear Autoregressive Moving Average with eXogenous inputs) model. The proposed controller is composed of an iterative learning neural identifier and an iterative learning controller. Iterative learning control and iterative learning identification ar...
متن کاملOn the convergence of iterative learning control
We derive frequency-domain criteria for the convergence of linear iterative learning control (ILC) on finite-time intervals that are less restrictive than existing ones in the literature. In particular, the former can be used to establish the convergence of ILC in certain cases where the latter are violated. The results cover ILC with non-causal filters and provide insights into the transient b...
