Since optical links are easily blocked by obstacles in the environment, they have been
considered difficult to directly perform wireless communications. However, reconfigurable …

It is difficult for free space optical communication to be applied in mobile communication due
to the obstruction of obstacles in the environment, which is expected to be solved by …

This paper introduces a frequency-weighting method for adaptive disturbance rejection. The
method constrains the high-frequency gain of the prediction filter in a minimum-variance …

This paper demonstrates high-performance adaptive control for a laser-beam steering
system, which exhibits high-order unknown jitter dynamics. The adaptive controller, which is …

When high performance is expected, vibrations are becoming a burning issue in adaptive
optics systems. For mitigation of these vibrations, in this paper, we propose a method to …

We propose a method to identify tip-tilt disturbance model for Linear Quadratic Gaussian
control. This identification method based on Levenberg–Marquardt method conducts with a …

This paper presents an adaptive control scheme for suppressing jitter in laser beams. The
variable-order adaptive controller is based on an adaptive lattice filter that implicitly identifies …

The paper presents a comparison of three new robust control approaches for a micro electro
mechanical system (MEMS) optical switch, considering uncertainties such as system …

In this paper, the control of a fast steering mirror, which is the core element of an adaptive
optics system, is investigated to suppress the beam jitter. The main source of the jitter is …

A modeling method is proposed for a dynamic fast steering mirror (FSM) system with dual
inputs and dual outputs. A physical model of the FSM system is derived based on first …
