Abstract
This paper presents a viewpoint on switching surface design in variable structure control. It gives a brief historical perspective about optimal control. The issue of constructing a switching surface has been addressed from different points of views by a number of researchers. One aspect that is not emphasized enough is the quest for optimality. Can the switching surface be made optimal; and if so, in what sense? Solutions with practical interest for linear composite systems (sub-systems or structures) are provided withing the framework of Linear Quadratic Regulator (LQR) theory.
