Adaptive collaborative compensator design method for human-machine system

The control performance of manual controlled human-machine system considerably depends on the skill level of human operator. So, authors have proposed a concept of ldquoCollaboraterrdquo which coexists with human operator as a parallel control element and can collaboratively control the machine in order to modify the response of human-machine system. In this report, for the variety of human dynamics, an adaptive collaborater using Neural Network is considered.

A formulation of dissipativity on pencil model

Abstract The concept of dissipativity and passivity is of interest from a theoretical as well as a practical point of view. In this paper, a formulation of dissipativity for linear time-invariant system on pencil model is derived. According to the structural properties of canonical form for pencils, it can be shown that a storage function is written as a quadratic form of the solution of the LMI which consists of the original system parameters.

A Behavioral Approach By Using Pencil Based System Models

Abstract In this article we consider the problem of analysis and design of linear time-invariant control systems by using the system models which are based on matrix pencils. Behaviors, poles, zeros, stability, controllability, observability, transfer function, and other traditional concepts are discussed mainly besed on the Willems’ behavioral approach. Moreover the extensions to LQ optimal control problem and computation of H norm are investigated.

Development of Eye Gaze Software for children with physical disabilities

Its not easy for physically disabled students to communicate with others. Aim of this study is to develop communication aid application for such disabled students. Some of disabled students can express his/her feelings with facial expression even though they cannot move their hands or fingers. For these students, eye movement is one of the most important channels of communication. Therefore we make a better communication aid application which detects eye movement using image processing techniques. Several applications that detect line-of-sight are proposed so far however, the cost of these applications are very high and cannot be used easily. In this study, a communication aid application is implemented on a tablet terminal. Our proposed communication aid application plays voice for the disabled student when our application detects eye-movement. This paper describes how our application works, its efficiency and our future work.

EXPERIMENTAL STUDY OF COLLABORATER IN HUMAN-MACHINE SYSTEM

Abstract A human intervention is essential for human-machine system and human operators skill affects deeply achievement of the control purpose. By keeping the human operation easy, an operator can concentrate on more advanced decision so that the operation performance is improved. In this paper, a new concept of human-oriented compensator is proposed for improving the human-machine system, which is named “collaborater”. The design approach exists in human dynamics, and 2DOF structure is introduced. The simulation results confirm that the time and frequency responses are improved. Moreover the experimental results also confirm the similar effect of proposed method.

CURRICULUM FOR SYSTEM CONTROL EDUCATION USING PROGRESS LINE TRACER

Abstract There have been literatures which have focused limited topics of control engineering, for example manipulating transfer function, considering stability etc. There have been also literatures to teach control engineering in the robotics. It seems to be no reports which has discussed the framework, curriculum for system control engineering education. This paper describes the design of curriculum for system control engineering of technical college in Japan. The feature of this curriculum is line tracer oriented. Furthermore, the goal of learning is cleared to student and line tracer is attractive. Improving examination of control engineering is also described shown in this paper.

Concept, structure and design of "collaborater" in human-machine system

Abstract A human intervention is essential for human-machine system and human operators skill affects deeply achievement of the control purpose. By keeping the human operation easy, an operator can concentrate on more advanced decision so that the operation performance is improved. In this paper, a new concept of human-oriented compensator is proposed for improving the human-machine system, which is named “collaborater”. The design approach exists in human dynamics, and 2DOF structure is introduced. The simulation results confirm that the time and frequency responses are improved. Moreover an adaptive function against changes of human dynamics is constructed using neural networks.
