Inverse dynamics for actuator control of a transformable structure in space

Abstract

This article proposes inverse dynamic calculation methods for actuator control of deployable structures and adaptive structures in space. The objective of this study is to estimate time change of an input moment controlled by an actuator which can gradually stop the transformation without acceleration and velocity at an assumed position and time so as not to cause structural vibration after the transformation. This article proposes three types of specific inverse calculation methods using trigonometric function and higher degree equations with their calculation examples which may be useful for design of an actuator considering deceleration control.
