Abstract

A laser diode package is mounted on an optical pickup head actuator. The laser diode
package is used to sense the displacement of a moving target by self-mixing interference signals. A
sliding mode based fuzzy control method is developed to achieve fast response of the optical pickup
head actuator, which is driven in a focusing direction. Simulation results show the proposed
method performs better than sliding-mode control. Experimental results further show that the
proposed control method outperforms sliding-mode control.
