Conceptual design of BCI in the formal basis of Hierarchical System

Conceptual Design of BCI for Mobile Robot Control

“…The conceptual model of the BCI system is briefly presented below, as an example of a biomechatronic system description in the theoretical basis of hierarchical systems (HS). The object under consideration in this work is the BCI system ( Figure 2), with its measuring, computer, man-operator, and mobile robot subsystems, developed in AGH University of Science and Technology, Poland [1,2]. Systemic conceptual model of the BCI system is given in aed form (6) of HS:…”

“…At the end of the 20th century, leading research centers around the world, i.e., Graz University of Technology, Austria; University of Rochester, USA; EPFL, Switzerland; etc., initiated research aimed at developing Brain Computer Interfaces-BCI, which provide communication between a computer and a human brain. In the presented work, we deal with the conceptual design of the laboratory-level BCI system created in Process Control Dept., AGH University of Science and Technology, Poland [1,2]. This BCI system consists of measuring and computer control subsystems, mobile robot (MR) and man-operator.…”

“…The results of the BCI system detailed design and MR control processes are described in the second part (Sections 2.2 and 2.3). A review of the literature on BCI systems will not be given in the paper since the focus of this work is to apply the Hierarchical Systems technology [2] to the BCI system design, which is a novel concept to this area of research.…”

“…Concerning the first part, the conceptual model of BCI being created at the conceptual design phase [2] must be coordinated with numerical and geometrical systems, taking into account connected mechanical, electro-mechanical, electronic, computer, and biological subsystems of BCI biomechatronic system. Besides, a conceptual model, which will be implemented in systems coordination (design and control), should describe all the subsystems, the mechanism of their interaction, technology of Appl.…”

“…Each process contains its lower-level sub-processes, e.g., ( π S 3 ) process of computer subsystem contains low-level −1 process of data reading π S −1 31 , digital filtering π S −1 32 , Fast Fourier Transformation π S −1 33 , signal spectral analysis π S −1 34 , frequency verification π S −1 35 , and generation of control signals for the mobile robot π S −1 36 . All these processes are described according to (2).…”
