Abstract
In this paper, we deal with active control of shock in a collision problem between two objects by applying control input to the shock-giving object. The goal of active shock control is to suppress the deformation of the shock-giving object and make the plastic deformation of the shock-receiving object large. The deformation ratio is defined as ratio of the plastic deformation of the shock-receiving object to the deformation of the shock-giving object. By using LQI control allowing deformation of the shock-giving object, the controller is designed. It is shown from the results of simulations that there is the maximum value in the deformation ratio standardized by the input energy with the change of weighting coefficient for the control input.
