強正実制御系設計のための等式制約を含まないLMI条件

抄録

Strictly positive real control problem is considered for a linear time-invariant plant, where an internally stabilizing controller is designed such that the resultant closed-loop transfer function is strictly positive real. The solvability condition of this problem includes not only inequality constraints but also equality constraints. This paper presents a necessary and sufficient condition for the existence of a controller in terms of strict linear matrix inequalities.
