To improve stability and convergence, feedback control is often incorporated with iterative learning control (ILC), resulting in feedback feed-forward ILC (FFILC). In this paper, a general form of FFILC is studied, comprising of two feedback controllers, a state feedback controller and a tracking error compensator, for the robustness and convergence along time direction, and an ILC for performa...

Discursive knowledge emerges as codification in flows of communication. The flows of communication are constrained and enabled by networks of communications as their historical manifestations at each moment of time. New publications modify the existing networks by changing the distributions of attributes and relations in document sets, while the networks are self-referentially updated along tra...

In order to improve the availability and productivity of manufacturing systems, process monitoring has become an important matter in modern automated plants. The traditional monitoring technologies are based on single sensors and are insufficient, especially for manufacturing processes of highly complicated and automated systems. Instead, multi-sensor based technologies are developing rapidly a...

in this article, the factors considered in the evaluating performance of urban management in ardabil are classified in two axes: 1. enabling and supporting entrepreneurs (with 10 components) and 2. providing the appropriate environment for entrepreneurs (with 6 components) and their importance are determined using the technique of multiple comparisons. the statistical population in this study a...

In this paper, we will show that contouring performance can be viewed as a regulation problem in a moving task coordinate frame that is attached to the desired contour. By transforming the machine tool feed drive dynamics to this task coordinate frame, a control law is designed to assign different dynamics to the tangential and normal directions. The transformation also illustrated the effect o...
