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
...

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 ...

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...

Adaptive and robust composite control of coordinated motion of space robot system with prismatic joint
Tập 2 - Trang 1255-1259 vol.2
In this paper, the coordinated control of the base attitude of the space robot
system with prismatic joint and arms is studied. Based on the momentum
conservation, the kinematics and dynamics of the system are analyzed. It is
shown that the generalized Jacobian matrix and dynamic equations of the system
can be linearly dependent on a group of inertial parameters. From the results
proposed above, t...

Real-time recognition of road traffic sign in moving scene image using genetic algorithm
Tập 2 - Trang 1027-1030 vol.2
This paper developed a new technology for the recognition of traffic sign from a
moving picture captured by a CCD camera in a car. In order to realize a
real-time position recognition, the genetic algorithm (GA) with search region
limits was employed to detect the position and size of traffic signs in
real-time, and a new image filter was used to extract specified colors. Through
experiments of ro...

Two-degree-of-freedom H/sub /spl infin// control of ship steering
Tập 1 - Trang 763-767 vol.1
The paper is concerned with an investigation into the use of two degree of
freedom (TDF) H/sub /spl infin// control theory to a ship autopilot design. The
method can overcome the computation difficulty of the classical H/sub /spl
infin// optimization method due to the origin pole of the ship model. The
presented TDF H/sub /spl infin// robust controller can guarantee the robustness
and the performa...

A lie-resisting evaluation and decision method in virtual enterprise
Tập 3 - Trang 2127-2131 vol.3
In real applications of the virtual enterprise, there are many lies when agents
negotiate with each other about tasks and rewards. To resist the lies, a general
evaluation and decision model and a correspondent method are proposed.
Negotiation data are not always trusted but evaluated by means of fuzzy
reasoning to decide whether and how much we should rely on it. Because fuzzy
rules are obtained ...
