Automatic Measurement System for Crater Wear Depth of a Throwaway Chip by the Optical Cut Method
Autor: Hiroyuki Okamoto, Yoh Yonezawa
Publikováno v: Journal of the Japan Society for Precision Engineering. 59:1643-1648
This paper describes a software design of an inexpensive automatic image processing system. In order to avoid the use of a threshold operation, center ordinates of strip images of objects are assessed by means of the weighted mean. Further, to decrea

An Indirect Method of Computing Time Optimal Control of Linear Systems Considering the Terminal Error Norm
Autor: Yoh Yonezawa, Yukio Nishimura
Publikováno v: Transactions of the Institute of Systems, Control and Information Engineers. 6:261-270
Eaton (1962) has solved theoretical problems in computing time-optimal control of linear systems. But in the practical point of view, his method has two main drawbacks with respect to both the convergent rate and the accuracy of the solution. In this

An Application of Time-Optimal Control by Using Switching Surface
Autor: Junso Kimura, Naoki Kushida, Yoh Yonezawa, Yukio Nishimura
Publikováno v: Transactions of the Institute of Systems, Control and Information Engineers. 5:400-409
The authors have previously proposed a design method of time-optimal feedback control system by using switching hypersurface. In the present paper, the proposed method is applied to construct the control system of the training ship Ohshimamaru 330 GT

A New Disturbance Compensating Method in Model Reference Adaptive Control System
Autor: Yukio Nishimura, Shuming Chen, Yoh Yonezawa
Publikováno v: Transactions of the Institute of Systems, Control and Information Engineers. 5:274-282
This paper proposes a design method of MRACS (Model Reference Adaptive Control System) for unknown plants in the presence of deterministic disturbance or periodic disturbance, so that the output error will converge to zero as time tends to infinity.I

Robustness of Double-Adaptive Observers
Autor: Yoh Yonezawa, Yukio Nishimura, Yong Li
Publikováno v: Transactions of the Institute of Systems, Control and Information Engineers. 5:507-512
The usual process identification methods for parameter adjustment, along with dead zone, are effective in providing a robust adaptive observer of an unknown plant under uncertain input disturbance and output measurement noise. But it is difficult to

A Design of Adaptive Identifier with Periodical Input
Autor: Yoh Yonezawa, Yukio Nishimura, Yong Li
Publikováno v: Transactions of the Institute of Systems, Control and Information Engineers. 5:122-130
In this paper, we consider the problem of continuous adaptive identification where a periodical 'test input signal can be used. First, we propose a design method of the gain matrix of the adjust rule for the Kreisselmeier's type adaptive identifier.
