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 ......

A novel learning method for special Bayesian networks
Tập 1 - Trang 37-42 vol.1
In this paper, a novel learning method for special Bayesian networks which consist of noisy-OR and noisy-AND nodes is introduced. This method can learn networks with hidden variables and discover hidden variables when necessary. Compared with previous techniques for learning Bayesian networks, it uses the information in the data to guide the search for useful revisions, and can greatly improve the......

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......

The transient stability analysis of power grid suffered from small-signal generating deviation
Tập 2 - Trang 1069-1072 vol.2
Under the environment of the electrical power market, every power plant inside the pool will deliver electrical energy to power grid following the daily generating plan. A variation from the plan of more than 2% is considered a generating deviation. This paper presents the classification of generating deviation, and in applying the principle of the small-signal stability, analyzes the effect of th......

Robust stabilization for perturbed discrete time-delay large-scale systems via dynamic output feedback control
Tập 4 - Trang 3299-3303 vol.4
Robust stabilization problem for a class of perturbed discrete large-scale systems with time-delays is discussed in this paper. Decentralized dynamic output feedback controllers and the tolerable bounds can be obtained simultaneously by means of a convex optimization involving linear matrix inequality. In addition, the effectiveness of the proposed approach is shown by a numerical example.
