Abstract
In this note symbolic-computation methods are used to design simple, fixed- structure, robust controllers for nonlinear systems. Design specifications are reduced to logically quantified polynomial inequalities: The quantifier -elimination (QE) software package QEPCAD is used to eliminate quantifiers on state and plant parameters, to obtain regions of admissible controllers parameters, that guarantee robust stability and performance.
