Analysis fuzzy-PID versus fuzzy for quadcopter altitude lock system

Mostly quadcopter has a flight controller to receive signal from remote control to control four brushless motor speed. in this paper,the researchers introduced a new control method to make quadcopter altitude lock system using fuzzy-pid and perform a comparative performance analysis between the fuzzy controller and the new fuzzy-pid controller. fuzzy controller has ability to solve uncertainty within the system,by incorporating with altitude sensor data. on the other hand,fuzzy-pid has the ability to gain the target level with kp,ki,kd values controlled. in this paper the researchers present an analysis to compare the control method between fuzzy and fuzzy-pid with regards to the stability altitude lock system. the stability of the altitude lock system can be measured by how small the oscillations occurred. fuzzy control has shown to produce better result than fuzzy-pid control. fuzzy control has 14 cm as its average oscillation,while fuzzy-pid recorded 24 cm as its average oscillation. © 2015 penerbit utm press. all rights reserved.
