摘要: Abstract The objective of this paper is to determine accuratly uncertainty domains and give a detailed analysis control them. A class uncertainties representing model errors or changes in operating conditions the systems has been examined. More precisely maximal permissible variations poles zeros have studied order maintain within admissible domains. Our approach illustrated by concrete case (an oscillating divergent system). robust optimization method shown reduce effects physical parameters variations. It demonstrated that Hnorm minimization equivalent interpolation right half plan [RHP] nominal system. All these concepts applied controllers for system
