Pi and Pd Controller Design for Fuzzy Gain and Phase Margin Specifications
نویسنده
چکیده
The paper addresses the problem of PI and PD controller design for linear systems with fuzzy parametric uncertainty. The plant model is considered as a possibility distribution on a plant space and closed loop specifications are given as a fuzzy set of interval gain or phase margins. A set of PI and PD controllers is found that meets the desired specification for each plant of fuzzy set of models. The solution is graphical in nature and uses frequency domain properties of interval control systems.

A Survey of Pid Controller Design Based on Gain and Phase Margins(invited Paper)
This paper focuses on the PID controller design based on the gain and phase margin (GPM) specifications for a given signalinput-signal-output plant. The basic ideas, techniques, and results are presented in language and notation familiar. Since the definitions of GPM equations are highly nonlinear, an analytical tuning method is not yet available. Approximation and fuzzy neural network (FNN) ap...

This research applied Proportion and Integration (PI) type fuzzy methods for mobile satellite antenna control system design. The detailed block diagram of a satellite antenna tracking system is very lousy; it is very difficult to obtain the key parameters for analyses and simulation. Thus a simplified model of antenna pitching or yawing control system is applied to speed up the design and obtai...
