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...... hiện toàn bộ

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...... hiện toàn bộ

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 ...... hiện toàn bộ

PID self-tuning control based on evolutionary programming
Tập 4 - Trang 3132-3135 vol.4
With the difficult in controlling dead-time and nonlinear system, a new method of fuzzy parameter self-tuning PID control which is based on the combination of evolutionary programming and fuzzy theory is proposed in this paper, it uses evolutionary programming directly to derive fuzzy rule bases of PID parameter tuning. To a certain extent, it overcomes the shortcoming of single fuzzy control and ...... hiện toàn bộ

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...... hiện toàn bộ
