Abstract
This paper proposes a vibration control method of PC case. Vibration of the PC influences its performance. Especially, the vibration caused in hard disk drive (HDD) degrades the positioning control accuracy. From this background, this paper introduces smart structures technology to the PC case, and attempts active control to suppress the vibration of the PC case. In this paper, vibration test is carried out to measure the vibration characteristics of the PC case. From the measured data, the location of the actuator is determined, and control system is constructed. To achieve high control performance, this paper designs two controllers with different design conditions and their control performances are compared.
