ILC可以看成是一种特殊形式的model-based policy gradient方法,假设我们通过某个轨迹规划方法算出一条:\begin{align} &u_k=\bar{u}_k-K_k(x_k-\bar{x}_k)\\ &\text{The latter can be any controller.} \end{align}\tag{1}通过ILC,我们只会修正\bar{u}_k而不会修改\bar{x}_k,最终的目标是...
The chapter presents original research results in the area of nonlinear iterative-learning control. We propose a novel ILC scheme developed using neural networks. The following two cases are described: dynamic and static learning controllers and in both cases the controller is designed in such a ...

An iterative learning controller based on feedback control is presented for a class of repetitive nonlinear time varying systems with uncertainty and disturbance. This iterative learning controller is designed to high order PD type and acts on plant as a feedforward. This paper gives the convergence...
This work is focused on the iterative learning control (ILC) design for linear discrete-time systems with iteration-varying factors, including reference, initial state, and exogenous disturbances. First, multiple high-order internal models (HOIMs) are given for various iteration-varying factors. The...
Initially, we propose the PD-type iterative learning controller together with initial state learning law, and sufficient condition to guarantee the convergence of tracking error is derived. Thereafter, a novel LQAT, with a high-gain property, for the model under consideration is constructed. The ...
