In this paper self-tuning fuzzy PID controller is developed to improved the performance for a pitch control of aircraft system. The controller is designed based on the dynamic modeling of system begins with a derivation of suitable mathematical model to describe the longitudinal motion of an aircraft. Fuzzy logic is used to tune each parameter of Proportional-integral-derivative (PID) controller by...
The use of Light Emitting Diode (LED) as the lighting device becomes popular due to its energy-efficient characteristic. However, LED has radiation angle that is relatively smaller than other types of lighting device. This results in heterogeneity of light intensity that received by particular point near the LED. To obtain homogeneity of light intensity, this paper proposes a model of fuzzy logic...
