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 ......

The principle and application of synergetic pattern recognition
Tập 4 - Trang 3122-3126 vol.4
The paper first expounds the principle of synergetic pattern recognition. Then it discusses the implementation techniques of the pathology image classification system based on the principle in detail. What's more, to resolve the problem that the synergetic neural network is weak in recognizing new test samples, it presents the information superposition self-learning algorithm based on a genetic al......

Transmitting power control based on control system framework in CDMA system
Tập 1 - Trang 597-601 vol.1
Surveys the research in transmitting power control (TPC) in CDMA cellular systems with an emphasis on the aspects of power controller design. First of all, some basic theories of power control are reviewed from the point of view of communication. Then the TPC problem is put in the standard framework of a control process, and quantities in TPC are treated as control system components. Most of the a......

Design of a 80C196KC-based DC motor PWM speed controller
Tập 2 - Trang 1497-1500 vol.2
A DC motor PWM speed controller based on 16-bit super capability single-chip microcomputer 80C196KC is presented. The practical application shows that the system has a simple structure and reliable speed regulation capability. The control algorithm of this system is easy to change, without changing the hardware. It also shows that the capability to price of this system is very high.
