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 ......

Design and implementation of an adaptive PID controller using single neuron learning algorithm
Tập 3 - Trang 2279-2283 vol.3
In this paper, an adaptive single neuron-based PID controller for DC motor systems in vibratory stress relief equipment is proposed. Three inputs of the single neuron, which accord respectively with the proportion, integration and derivative of the feedback error, are associated with variable weights. The weight training algorithm is based on a combination of Delta and Hebbian learning rules. A mo......

Bio-reflex-based robot adaptive motion controlling theory
Tập 3 - Trang 2496-2499 vol.3
The environment adaptability of robot motion can be effectively improved with bio-reflex theory which is a new research direction of robot motion-control. The paper introduces the basic theory of complete adaptive motion of robot with bio-reflex mechanism. As for the motion control of the robot, the traditional and the bio-reflex control methods are compared. The concept of a single system and its......

The study of swing up and balance control for rotary parallel inverted-pendulum
Tập 3 - Trang 2370-2374 vol.3
The paper presents the swing up controllers with pendulums that can be designed separately through the analysis of the nonlinear dynamic model of the pendulum system, It is better to swing up the long link first than to swing up the short link first. So the swing up controllers are designed based on the energy control theory and linear quadratic optimal controllers are used to stable the pendulum ......

Design of a new controller based on D-S evidential theory
Tập 4 - Trang 3093-3095 vol.4
The single-input and single-output loop controller using only one sensor is widely applied in the industrial control field. As it is difficult to obtain the precise response of the control using only one sensor, the result cannot satisfy the demand. In the multi-sensors system, one must solve the problem of fusing different uncertainty data. This paper discusses a new design method for the control......

Stability analysis for interval descriptor systems: a matrix inequalities approach
Tập 2 - Trang 1007-1011 vol.2
This paper considers the stability analysis and quadratic stabilization problem for a class of interval descriptor systems. It derives a sufficient condition for the interval descriptor systems to be quadratically admissible. Then, the conditions for the interval descriptor systems to be quadratically stabilizable are established. Two numerical examples are used to illustrate the main results.
