Iterative Learning Control Systems

We propose a redesign method for modal parameters to depress the second resonance peak of an ultraslim optical pickup actuator. With the addition of the countermode near the second resonance frequency, we can achieve the gain margin, which is sufficient to meet the system requirement. It would alleviate the burden of the additional filter for a high-speed drive.
