Main Research Topics:
Repetitive control and its application
|
This topic involves designing a repetitive
control system that can reject non-periodic disturbances. Repetitive control is a very useful strategy for tracking periodic
reference inputs and rejecting periodic disturbances. However, a
repetitive control system cannot readily reject non-periodic
disturbances. We investigate the influence of non-periodic
disturbances, new approaches to disturbance
estimation, and new design
methods for repetitive
control systems. Furthermore, we apply these methods to
the construction of rotational control systems to boost their
performance and precision. |
Application of advanced control theories
|
This topic involves developing
advanced control techniques for practical use. We examine how to
apply new control theories, for example, robust control, nonlinear control, intelligent control,
etc., to mechatronic systems, such as an inverted pendulum, a
magnetic levitation system and an arm robot. |
Expert control systems
|
This concerns the design of expert control
systems for chemical processes. Chemical processes involve complex chemical
reactions, and are difficult to describe precisely with
mathematical models. So, conventional control methods, which are
mainly based on manual operation and mathematical models, do not
yield the desired control performance. We
construct expert control systems that combine rule models and
steady-state mathematical models in order to produce both a high-quality product and significant economic
benefits. |
Motion control of acrobots
|
This topic involves designing optimal control
laws for acrobots. Due to
the complexity of the nonlinear dynamics and the nonholonomic
behavior of an acrobot, it is very difficult to control its
motion. We are trying to develop design methods for controlling an acrobot
that do not need to divide the motion space into subspaces. |
Construction of an on-line control education system
|
This topic involves investigating how to use
Internet experimental systems in an on-line course. Our goal is
to develop an on-line control course, which employs Internet
experimental systems, in conjunction with universities in China and Japan. |
j-Pinyin
|
This topic involves constructing an intelligent
input support system and a Japanese-Chinese/Chinese-Japanese
dictionary for Chinese proper nouns. In Japan, there are no general rules for writing the pronunciation of Chinese proper nouns
(the names of people/places, etc.). We have proposed a new Japanese kana notation, called
j-pinyin, based on an international view point and taking into
account the needs of the media. Future plans call for improvement
of the j-pinyin system based on experimental results and the
construction of an input support system and
dictionary. |
