安定余裕を指定した部分極配置

多項式ILQ設計法の拡張

抄録

This paper proposes a design method of a state feedback gain which simultaneously achieves specified gain and phase margins and partial pole placement. Gain and phase margins are guaranteed by imposing quadratic constraints on open-loop transfer functions. Also, partial pole placement is done by using the same gain parametrization as in the polynomial ILQ method. It is shown that our design problem is formulated as a feasibility problem with LMI constraints and a non-linear equality constraint.
