摘要

Stable control of large flexible structures has long been a challenge. Even though other research showed that direct velocity control and then position-and-velocity control are feasible, they require perfect or almost perfect collocation of velocity sensors and actuators. A very simple parallel feedforward device, which uses basic stabilizability properties of systems in order to allow implementation of strict positive real configurations, is tested here and is shown to eliminate the need for velocity feedback and collocation.
