The performance of PID and fuzzycontrollers is compared in a commercialdevice normally used in modelairplanes: the S3004 Futaba Servo.The controller circuit, the poweramplifier and the sensor are modified,and then the motor is observed. Next,a root-locus method is used to tunea PID for angular position control.Simulations and control are made inMatlab’s Simulink, and also a dataacquisition card (PCI 6024E) is used.Results are analyzed at the end of thedocument: although the PID controllerworks better, the fuzzy controllershows a similar performance.
