Abstract: This paper focuses on the iterative learning tracking control problem for a class of nonlinear system with time-varying disturbances. First, because of the mismatches in time-varying disturbances functions, a high-order feed-forward iterative learning control (ILC) is employed to change the original system into an iterative system. Secondly, a variable forgetting factor is developed to stabilize the system. Based on the feed-forward iterative learning controller, a memory controller is constructed for the nonlinear system. By choosing a new variable forgetting factor, we show that the designed continuous adaptive controller makes the solutions of the closed-loop system convergent to a ball exponentially. Finally, a numerical example is given to show the feasibility and effectiveness of the proposed method.

Abstract: This research has focused on the idea of Groupware Matrix and Roomware and placed them in the field of integrated design of real, physical, architectural spaces and virtual, digital information spaces. Roomware main idea is the computer-augmented components in rooms, e.g. furniture. The general approach is to gather information via examples from i-LAND project where developing various Roomware devices to introduce the meaning and the use of interactive information and cooperation design. It describe i-LAND that consists of DynaWall, Interact able, and ComChair. i-LAND requires and provides other components of human-computer interaction and new forms of computer-supported cooperative work (CSCW). This helps the designer to gather information from architectural spaces and implement a new work practices and design. i-LAND also consists of various “Roomware” components, i.e. computer-augmented objects integrating room elements with information technology. It present the current realization of i-LAND as an interactive electronic wall, an interactive table, and two computer-enhanced chairs.
