A fast-settling control method for the fine actuator system in an optical disc drive has been developed. The fast-settling control is performed by two-degree-of-freedom control, which uses the reference trajectory. The reference trajectory according to the initial state at mode switching between seeking and settling is determined by using a final-state control. Tests with a 16x DVD-ROM drive experimentally confirm that the proposed settling control significantly improves the settling capability.
