Abstract

There is a need for the controller optimization of the evaluation test of optical image stabilization (OIS) actuators. However, in the field where only the actuator and not the entire OIS module is designed, the performance evaluation is inconvenient because no system for evaluating the prototype through controller design exists. Therefore, in this study, we developed a system and a program to design and evaluate the OIS control algorithm executed in an independent environment without complex configuration. For the program design, a controller design system was developed based on the basic control theory, and a graphic user interface was produced and programmed such that the controller could be designed and evaluated using only parameters without complications.

Keywords:

Optical image stabilization (OIS), System identification, Control design, Closed loop performance
