Design of a Fuzzy Controller for Stabilizing a Ball-and-Beam System'
نویسنده
چکیده
This paper presents the stability analysis and design of fuzzy controller for a nonlinear ball-and beam-system. An improved simple stability condition will be derived based on the Lyapunov's stability theory. The derived stability condition involves a smaller number of Lyapunov's conditions. A design of the membership functions of the fuzzy controller will be given. In our approach, the number of rules of the fuzzy controller can he different from that of the fuzzy plant model. In addition, our approach can be applied to those fuzzy controllers with both positive and negative grades of membership.

متن کاملDesign Supplementary Controller Based on Stabilizing Effect of Delay for Damping Inter Area Oscillations in a Power System
The delay associated with signal transmission through the wide-area measurement system reduces the functionality of the power oscillation damping control system. One of the important issues is the poor operation of the supplementary controller against delay existence, which limits the efficiency of damping of ancillary equipment, such as SVCs in a power system. This paper as a solution proposes...
