Optimal feedback design under bounded control

We study the static state feedback design problem for linear systems under given constraints on the magnitude of the control input. A quadratic performance index is constructed such that it is optimized by the synthesized control. The issues of fragility of the controller are analyzed; this phenomenon relates to the loss of the stabilizability property of a controller under small variations of its parameters. Linear matrix inequalities are used as a main technical tool.
