Abstract :
A method is proposed for synthesizing a controller, whose order is a priori fixed, and which ensures a robust pole placement inside a given region of the complex plane, despite parametric uncertainties in the plant model. The key idea is to use a dyadic parametrization of the controller, so as to transform the non-convex optimization problem into a series of linear programming problems. The method is successfully applied to the space shuttle example presented in the User´s Guide of the MATLAB μ-analysis and synthesis Toolbox
