Induction motor drives with direct torque control based on adaptive fuzzy control
Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 4 - Trang 2991-2995 vol.4
Xia Yang, Zhang Tianping, Tang Hongru
This paper presents an application of the adaptive fuzzy inference system to an induction motor speed control system based on direct torque control. For practical implementation of the control strategy the triangular fuzzy membership functions were adopted instead of the Gaussian's one in the fuzzy system. The control law and adaptation law were derived by the system stability analysis, which ensu...... hiện toàn bộ

H/sub /spl infin// identification for nonlinear system based on generalized frequency response function
Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 1 - Trang 114-118 vol.1 - 2002
Wen Ou, Chongzhao Han, Min Chen
Based on the GFRF (generalized frequency response function), H/sub /spl infin// identification for nonlinear system is investigated using the set membership identification theory. We applied the three-order truncated Volterra series to describe the nonlinear system, and accomplished the model identification by the Householder transformation that is a kind of orthogonal decomposition, and then deri...... hiện toàn bộ

Learning control of failure avoidance problems with known analytical form of cost function
Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 2 - Trang 950-954 vol.2
Derong Liu
We study adaptive critic designs for a class of failure avoidance control problems. We categorize such problems by the choice of local cost function as zero throughout a trial except at the last time step when a failure occurs. We derive an analytical form of its overall cost function defined as the infinite summation of the local cost function over time. We demonstrate that the outputs of the cri...... hiện toàn bộ

Maximum algebra of random variables with its applications in discrete event systems
Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 3 - Trang 2427-2429 vol.3
Yingwen Zheng
A maximum algebra of random variables, which can be used to analyse the manufacturing processes in discrete event stochastic dynamic systems, is presented. A kind of series-parallel production line systems in which the work durations of all tasks are random variables with exponential distributions is discussed. By means of the maximum algebra of random variables the statistical characteristics of ...... hiện toàn bộ
