A torque transmission system, which is composed of serveral gears and couplings, is flexible. Therefore, the transient vibration occurs when the motor velocity abruptly changes. To a transient vibration suppression, various control method have been proposed. Specially, one method of vibration suppression used disturbance observer filter. This method is torsion torque passing disturbance observer filter. By feedback of the estimated torsion torque, the vibration can be suppressed. In this paper, we used fuzzy controller. We proved of this approach is confirmed by simulation.

The current study investigates the mediating effect of negative emotions (depression, anxiety, and anger) in the relationship between long working hours and binge eating behavior in order to examine the effect of long working hours on individual health. Two hundred four workers completed questionnaire about working hours, depression, anger, anxiety, and binge eating behavior. Results confirmed the most employees work more than 10 hours at least once a month. Additionally, it was found that depression, anger, and anxiety all partially mediate the relationship between long working hours and binge eating behavior. The results indicate that long working hours influences negative emotions that leads to binge eating behavior.
