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
...

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...

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.

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 ...

A MES design based multi-Agent system
Tập 4 - Trang 2655-2659 vol.4
As a center of enterprise integration, the manufacturing execution system (MES)
integrated with the organisation layer and production layer business software
forms a total solution of enterprise scheme. However, MES still can not meet the
expectations of application completely. This paper presents a solution based on
the multi-agent system, by which MES can be implemented better for its many
virtu...

PCB infrared thermal imaging diagnosis using support vector classifier
Tập 4 - Trang 2718-2722 vol.4
A printed circuit board (PCB) diagnosis system based on infrared thermal imaging
is described. Multi-scale edge detection and nonlinear regression methods are
used for heat source recognition and thermal feature extraction respectively.
Thermal pattern recognition is implemented by support vector classifier instead
of traditional back-propagation feed-forward network classifier and a good
experime...

Study on bandwidth allocation optimization of FF acyclic communication
Tập 4 - Trang 2794-2798 vol.4
In process control application of FF, in order to ensure that acyclic
communication with critical time constraints is met, the bandwidth proportion
allocated to acyclic communication is oversized, which lead to waste of
bandwidth. For the sake of improving bandwidth availability of FF, in this
paper, based on priority mechanism, bandwidth allocation of FF is analyzed, and
two bandwidth allocation ...

A new error-correcting decoder for fast correcting codes with multi-bit errors
Tập 3 - Trang 2361-2364 vol.3
This paper introduced a new error-correcting technology with strong correcting
ability in digital signal transmission. We propose a decoding method by
shortening the code and full combination logic instead of using a lot of
shifting registers as we do in the traditional error-correcting circuit. As a
result, the error-correcting circuit is simplified and the error-correcting time
is greatly shorte...
