PURPOSE: A method for controlling locations finely in an actuator system is provided to provide an adaptive disturbance observer to be adapted to the parameter change or the disturbance. CONSTITUTION: The method for controlling locations finely in an actuator system use the method of estimating the disturbance by changing current input variable of the observer in the adaptive disturbance observer. The method use a dead-bit type adaptive controller to make response speed rapid. The method construct real system to follow-up interest model and the observer to adaptive model. The tracking controller feedback state variable using output errors additionally thereby being adapted to parameter change or the disturbance.
