Frequency domain iterative learning control for direct-drive robots

2003 European Control Conference (ECC), 2003
This paper presents an Iterative Learning Control algorithm for direct-drive robots. The learning algorithm assumes linear dynamics, which is created using a nonlinear model-based compensator. The convergence criterion of the learning controller is derived in the frequency domain.

A frequency domain iterative learning control for low bandwidth system

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
A frequency-domain learning scheme based on the modified Fourier series for the tracking control of system with a low bandwidth limit is presented. The proposed controller consists of two parts: a PD controller, and an online updated learning controller. The proposed method can reduce the tracking error more effectively than the same type of controller

Contrastive Learning in Frequency Domain for Non-I.I.D. Image Classification

2021
Non-I.I.D. image classification is an important research topic for both academic and industrial communities. However, it is a very challenging task, as it violates the famous hypothesis of independent and identically distributed (I.I.D.) in conventional machine learning, and the classifier minimizing empirical errors on training images does not perform

A generalized frequency domain learning control design with experimental validation

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
This paper presents a generalized iterative learning control (ILC) design in the frequency domain with experimental validation. The optimal ILC learning function and robustness filter function are simultaneously optimized by solving a linear programming problem using frequency response functions.

Learning Attention in the Frequency Domain for Flexible Real Photograph Denoising

IEEE Transactions on Image Processing
Recent advancements in deep learning techniques have pushed forward the frontiers of real photograph denoising. However, due to the inherent pooling operations in the spatial domain, current CNN-based denoisers are biased towards focusing on low-frequency representations, while discarding the high-frequency components.
