Abstract
An optical image stabilizing (OIS) system using fuzzy sliding-mode controller (FSMC) is presented in this research. The OIS system shifts the image sensor to correct the deviation from the optical path caused by a user's handshake vibration. The voice coil motors (VCM) was adopted to drive the OIS module which bears the image sensor, a gyroscope was used to detect the hand-shake vibration, and two single-axis hall sensors were designed to sense the position of the VCM actuators. The proposed FSMC overcomes the nonlinear, hysteresis, and time-varying properties of the VCM actuator efficiently. The stabilizing performance was demonstrated by digital photographs taken under different test conditions.
