In this paper we propose a new method of parameter space design for robust control synthesis, in particular in terms of real stability radius, using quantifier elimination (QE). We also aim at practicality by employing the scheme to combine the sign definition condition (SDC) and a special QE algorithm using Sturm-Habicht sequence. The validity of our approach is confirmed by some concrete examples.
Keywords: parameter space design, robust control design, stability radius, sign definite condition, quantifier elimination, Sturm-Habicht sequence
