Abstract
An optimization method is presented to design a minimum weight structure with constraints imposed on the closed-loop frequency distribution and damping parameters. The control approach used here is linear quadratic regulator theory. The control model reduction is achieved by using Model Error Sensitivity Suppresssion. The application of the method is illustrated by designing the structure for different order of control models with the same constraints. The different designs obtained by these approaches are compared. The optimization problem is solved by using a nonlinear mathematical approach.
