| Summary: | 碩士 === 國立臺灣大學 === 機械工程學研究所 === 90 === Pulse Mode is an efficient power-saving mode of CDROM track following. This thesis addresses pulse mode servo strategy analysis based on an optical drive dual actuator system. Furthermore, we discuss the stability of pulse mode tracking in the view of Lyapunov Stability Theorem. Then we do some pulse mode tracking simulations by using the ramp input reference model. At the same time, we consider several nonlinear conditions such as saturation, friction, and backlash, etc. At last, we sum up all the results and work out the strategy of deciding the pulse specification. The experimental results show the pulse mode strategy is correct and useable.
