| Summary: | 碩士 === 國立交通大學 === 電機與控制工程學系 === 86 === In this thesis, a method for reducing the run-out influence
due to the tracking servo control system is investigated.
Because the run-out signal is priodic, we use the repetitive
control algorithm forreducing it without changing the original
controller structure . This thesis contains two major parts .
The first part deals with the system standard, the circuit
analysis and mathematical modelling of the pick-uphead by the
Matlab and DSA(Dynamic system Analyser). The second part,deals
with the simulation and the practical implementation. We applied
the repetitive control algorithm to the tracking control loop of
the CD-ROM by TI DSK50 Kit. Experimental results clearly
demonstrate that the developed method can reduce the tracking
error successfully. Discussionabout the implementation in the
real controller are also given.
