Simulated robotic hot-line maintenance based on virtual reality
Tập 2 - Trang 1231-1235 vol.2
We construct a simulation system for a live line maintenance robot using virtual
reality. The simulation system uses the same input devices and controllers as a
real robot system. It provides functions of operator training, human-machine
intelligent control simulation, and robotic trajectory simulation. Those
simulation data can activate the real robot. The simulation system framework and
modeling...

Design of a mixed distributed computer control system
Tập 4 - Trang 2782-2785 vol.4
In the field of industrial automation, fieldbus is changing the traditional
DCS's important position and the architecture of distributed computer control
system. However, it is not the time that fieldbus is popularized widely in China
because of the factors of economy, technology and industrial automatic level.
Therefore, this paper presents a mixed distributed computer control system that
is comp...

Study on electrohydraulic servo loading system using fuzzy model based predictive control with multi-step linearization
Tập 1 - Trang 312-315 vol.1
Aimed at a multi-channel loading system, a fuzzy model based predictive control
with multi-step linearization scheme is proposed. Using a Takagi-Sugeno fuzzy
model as a predictive model of the loading system, a linearized fuzzy model with
multi-step, the predictive control is applied to the loading system. The result
of tests show that this scheme can effectively overcome the unknown influence of
...

Reheated temperature adaptive fuzzy control system of unit
Tập 1 - Trang 391-395 vol.1
The purpose of this paper is to solve the control problem on the reheated
temperature of unit which has such characteristics of time-varying, time delay
and multi-disturbance, etc. The traditional control and general fuzzy control
are difficult to dispose these matters that the model is time-varying, and the
fuzzy rule number increases sharply with the increasing systemic variable
number, so that ...

Matrix bounds for the coupled algebraic Riccati equation
Tập 1 - Trang 180-183 vol.1
In this note, we propose lower and upper matrix bounds for the positive
semidefinite solution of the unified coupled algebraic Riccati equation (UCARE).
Using the results of this note, computational algorithms to solve the UCARE can
be established.

Model identification and PID control of long time-delay processes
Tập 2 - Trang 900-904 vol.2
A relay feedback identification auto-tuning of PID/PI controller is proposed in
this paper, which is capable of controlling long time-delay processes. The real
process is approximated via FOPDT or SOPDT models, whose parameters are
specified through a modified relay feedback identification method. Applying the
zero-pole cancellation principle, the PID/PI controller is tuned according to
the specif...

Research on adaptive heuristic critic algorithms and its applications
Tập 1 - Trang 345-349 vol.1
The concept of reinforcement learning comes from behavior psychology that takes
behavior learning as trial and error, by which the states of environment are
mapped into corresponding actions. There's a question of how the behaviorism is
used to learn the actions in interaction with the environment in designing
intelligent robot. In this paper, the actions that robot takes to avoid
obstacles are ta...

Writer identification using Gabor wavelet
Tập 3 - Trang 2061-2064 vol.3
This paper focuses on a system to fulfill writer identification, which
identifies a person with his/her handwriting. A text independent method is
proposed in this paper, which involves no local feature analysis. First, a
preprocessing method is employed to normalize script images. Then, 2D Gabor
wavelet technique is developed to extract the global features. Finally a
K-nearest neighbor (K-NN) clas...

Application of support vector machine nonlinear classifier to fault diagnoses
Tập 4 - Trang 2697-2700 vol.4
Support vector machine (SVM) is a novel machine learning method based on
statistical learning theory. SVM is a powerful tool for solving problems with
small samples, nonlinearities and local minima, and is of excellent performance
in classification. In the paper, the SVM nonlinear classification algorithm is
reviewed. The SVM nonlinear classifier is applied to deal with fault diagnosis.
SVM is eas...

Robust decentralized control for a class of large-scale systems with mismatched uncertainties
Tập 2 - Trang 927-930 vol.2
The problem of robust decentralized control for a class of large-scale systems
with matched and mismatched uncertainties is considered in this paper. The
system under consideration possesses uncertainties in every subsystem and in the
interconnections. The uncertainties may be nonlinear, time varying and bounded.
The required information on uncertainties is merely that they are bounded by the
know...
