Sinusoidal rotatory chair system by an auto-tuning fuzzy PID controller

This paper presents DC servo motor speed control characteristics by fuzzy logic controller and considers position following control response with controller. A sinusoidal rotatory chair system using an auto-tuning fuzzy PID control was designed to evaluate the vestibular function. Then the system is investigated for the effects of change by the fuzziness of the fuzzy variable. If this system is supported by a channel, it is considered for application in industry where multi-joint robot and precision parallel driving are needed.
