Dealing with actuator rate limits. Towards IQC-based analysis of aircraft-pilot system stability [PDF]

INCAS Bulletin, 2013
The study continues the recent work of the authors, by sketching an approach of the aircraft-pilot system stability analysis, considering both the rate saturation of the actuator and the time delay in control input.

Stroke saturation on a MEMS deformable mirror for woofer-tweeter adaptive optics

, 2009
High-contrast imaging of extrasolar planet candidates around a main-sequence star has recently been realized from the ground using current adaptive optics (AO) systems. Advancing such observations will be a task for the Gemini Planet Imager, an upcoming "

Stabilization of motion control system with rate limiter using linear reference model

Nihon Kikai Gakkai ronbunshu, 2015
Actuator rate saturation has characteristics to increase the phase lag of the system and it can be one of the factors that destabilize the motion control system for a higher control response.
