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...

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 ...

Study and development on detecting device of wire rope localized fault
Tập 1 - Trang 704-707 vol.1
The wire rope is widely used in harbors, ships, and many industrial fields. The
safety of wire rope closely relates to the life safety and equipment safety.
Therefore, the fault detection of wire rope is always study focus in the NDT
area. The paper presents a new instrument for localized fault detection of wire
rope. By the special structure of detecting transducer, the interfere signal
from the ...

A nonlinear PID controller for CSTR using local model networks
Tập 4 - Trang 3278-3282 vol.4
The basic PID controllers have difficulty in dealing with problems that appear
in complex nonlinear processes. This paper presents a practical nonlinear PID
controller that deals with these nonlinear difficulties. It utilises a local
model (LM) network, which combines a set of local models within an artificial
neural network (ANN) structure, to adaptively characterise the process
nonlinearity. The...

Robust nonlinear control for bank-to-turn missile
Tập 4 - Trang 2973-2977 vol.4
Based on the two-timescale assumption, the dynamics of the Bank-to-Turn (BTT)
missile are firstly separated into two parts: the dynamics of fast states and
the dynamics of slow states. The velocities of BTT missile are chosen as state
variables of the slow dynamics. The aerodynamic force coefficients are not
linearized. First, the dynamics of fast states and the dynamics of slow states
are lineari...
