Anti-windup PI controller for millimeter-wave adaptive optics: a Nobeyama 45 m radio telescope simulation
Ichiro Jikuya, Yoichi Tamura, Akio Taniguchi +8
This work addresses the control problem for Millimeter-wave Adaptive Optics (MAO), which we define as compensating for the distance variation between the primary reflector (M1) and…

Millimeter-wave adaptive optics: Demonstrating closed-loop correction for lowest Zernike modes
Yoichi Tamura, Akio Taniguchi, Kotaro Iwakami +15
We report on a five-element prototype wavefront sensor for millimeter-wave adaptive optics (MAO), enabling closed-loop correction of tip-tilt and defocus via secondary mirror (M2)…
