Abstract

Based on the simulation relationship between LQ disercte time control and substructural chain instructural mechanics^1,2,3,this paper describes two equivalent formulations of algebraic Riccatiequation.The potential formulation is applied to develop the stiffness shifting method.By using thestiffness shifting method and proper transformations, the Riccati equation of singular control problem is derived.
