介紹管理方案的目標 Therefore, we developed a sliding motor control (SMC) method based on the position estimation algorithm (PEA) for use in AF of the linear actuator in a DVC to achieve low power consumption, high operational efficiency and fast dynamic AF access characteristics. 管理方案方法論的細節描述 A concrete and linear actuator with low power consumption and high operational efficiency was manufactured for AF in a DVC. A magneto-resistive (MR) encoder in the linear actuator was then adopted for use as a position feedback sensor to acquire the position of the moving part of the linear actuator in AF operation. Next, an interpolation chip was embedded to enhance the resolution of a linear actuator in a DVC, attain an enhanced image and avoid an increasing prime cost of a DVC. Additionally, the PEA was developed from the MR encoder to determine accurately the position of the moving part of the linear actuator in a DVC. 管理方案主要成果總結 According to our results, the proposed SMC method can offer an effective means of positioning and controlling velocity owing to its many advantages, e.g., insensitivity to parameter variations, disturbance rejection and fast dynamic response. Hence, the SMC based on the PEA written in a single chip can enhance control performance in order to increase focusing speed and accuracy. Additionally, the proposed SMC method can be adopted to manufacture a linear actuator with low power consumption and high operational efficiency for AF operation in a DVC. The proposed PEA can also determine accurately the position of a moving part of a linear actuator in a DVC. Moreover, the SMC method based on use of the PEA in AF operation in a DVC can reduce AF access time by several microseconds and avoid the recording of acoustic noise interference into the digital films. 管理方案對特定部門或領域的全面貢獻 Importantly, the proposed method is highly promising for use in manufacturing an efficient linear actuator with low power consumption and high operational efficiency for AF operation in DVC rapidly. Furthermore, the AF system with a linear actuator has a fast dynamic AF speed and limited acoustic noise interference.
