| Descripción: | Fuzzy logic control technology has been widely and successfully utilized in numerous industrial applications. Since fuzzy logic with humanlike but systematic properties can convert linguistic control rule based on expert knowledge into automatic control strategies, it can be well applied to control the process with un modeled and nonlinear dynamics. In this paper a fuzzy logic based pre compensation scheme for PID controller is proposed. Fuzzy methods can be used effectively to implement conventional control methods for performance improvement. The scheme is based on graphically studying the source of steady state errors arising from applying PID type schemes of systems with dead zones. This work is based on trying to compensate for overshoot and undershoot by the transient response. This is easy to implement in practice since an existing PID controller can be used in conjunction with the fuzzy pre compensator without modification Keywords: Fuzzy controller, PID Controller ,Fuzzification, Defuzzification. |
