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.

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 ...

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...

Processing of unperfected experimental data
Tập 3 - Trang 2217-2221 vol.3
A synthetic approach to processing the experimental data is discussed in this
paper. The mathematical statistics, fuzzy mathematics and artificial neural
network technique are synthesized together in order to process a kind of
unperfected experimental data, and a mathematical model in the shape of fuzzy
neural networks is built. This method then is used to process the experimental
data obtained fr...

Guaranteed-cost design based on T-S fuzzy model
Tập 3 - Trang 1862-1866 vol.3
Using a guaranteed cost control approach, the problem of Takagi-Sugeno (T-S)
fuzzy controller design via Linear Matrix Inequalities (LMIS) is presented in
this paper. The feedback control law is obtained through solving LMIS. This
method not only has guaranteed stability, but also minimizes an upper bound on a
linear quadratic performance measure. The example for a fuzzy controller of the
inverted...

The identification of frequency domain model of ultrasonic vibration system
Tập 1 - Trang 111-113 vol.1
The identification of frequency domain model of ultrasonic vibration system by
using least square method is discussed. The key frequency band is subdivided, in
order to keep characteristic point of system invariability. An actual vibrating
body is checked up, and the model coincides with the experiment result well.
This identifying model can be extensively applied to many fields.

Observer based adaptive controller design of flexible manipulators using time-delay neuro-fuzzy networks
Tập 2 - Trang 1241-1245 vol.2
A dynamical time-delay neuro-fuzzy controller is proposed for the adaptive
control of a flexible manipulator. It is assumed that the robotic manipulator
has only joint angle position measurements. A linear observer is used to
estimate the robot joint angle velocity. For perfect tracking control of the
robot, an output redefinition approach is used in the adaptive controller design
using time-delay...
