A -90 dBc@ 10 kHz Phase Noise Fractional-N Frequency Synthesizer with Accurate Loop Bandwidth Control Circuit
Autor: Koji Okamoto, Yuuji Yamada, Takashi Morie, Shiro Dosho, Kazuaki Sogawa
Publikováno v: IEICE Transactions on Electronics. :739-745
This paper describes a -90dBc@10kHz phase noise fractional-N frequency synthesizer of 110M-180MHz output with accurate loop bandwidth control. Stable phase noise characteristics are achieved by controlling the bandwidth correctly, even if the PLL use

Intelligent Adaptive Control for a Pneumatic Servo System
Autor: Yuuji Yamada
Publikováno v: TRANSACTIONS OF THE JAPAN FLUID POWER SYSTEM SOCIETY. 34:1-7
In this paper, we propose a design scheme for the intelligent control for a pneumatic servo system. In this design scheme, the unknown parameters are identified first and then the plant model is determined whether to be minimum-phase or not, because

Switching-type Adaptive Control for Pneumatic Servo System with Additive External Forces
Autor: Masaru Sakamoto, Shigeru Uchikado, Kanya Tanaka, Yuuji Yamada
Publikováno v: IFAC Proceedings Volumes. 30:145-150
In this paper, we propose a design scheme of a switching-type adaptive control for a pneumatic servo system with additive external forces. In this design scheme, the unknown parameters are identified at first and the plant model is decided whether to

Significance of the expression of proliferation-associated nucleolar antigen p120 in human colorectal tumors
Autor: Yoshifumi Nakayama, Yoshikazu Sugimoto, Yuuji Yamada, Ken-ichi Matsuo, Takashi Ueki, Kimitoshi Kohno, Yoriaki Sugao, Masazumi Tsuneyoshi, Michihiko Kuwano
Publikováno v: Human Pathology. 28:74-79
Nucleolar protein p120 is considered to be associated with cell proliferation and has also been detected in a broad range of human malignant cells and tissues, but not in either normal resting tissue or most benign tumors. To clarify the significance

Multirate Adaptive Pole-Placement Control for Pneumatic Servo System
Autor: Akira Shimizu, Kanya Tanaka, Yuuji Yamada
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C. 62:2186-2192
In pneumatic servo systems, the adaptive pole-placement control is applied to improve the control performance. However disturbances are not considered in the conventional design scheme of the adaptive control. Thus, an improved design schemes is prop
