Design of Fuzzy Logic PD Controller for a Position Control System
Absal Nabi · 2013
Conventional control system design depends upon the development of a mathematical description of the system’s behavior. This usually involves assumptions being made in relation to the system dynamics and any non-linear behavior that may occur. Fuzzy logic is the application of logic to imprecision and has found application in control system design in the form of Fuzzy Logic Controllers(FLCs) Fuzzy logic controllers facilitate the application of human expert knowledge, gained through experience, intuition or experimentation, to a control problem. In this paper a conventional proportionalderivative(PD)controller and a heuristically-tuned fuzzy logic PD controller for a position control system were derived and simulated using MATLAB-Simulink so that suitable comparisons could be made.
