Abstract
This paper addresses an assignment problem of characteristic multipliers for continuous-time linear periodic systems by linear periodic state feedback. The authors have proposed a, feedback control law by a method of raising frequency which enables to approximate the solution to a closed-loop system to the solution to a prescribed linear time-invariant system. This suggests that the feedback control by raising frequency may also approximately assign characteristic multipliers to a prescribed set of complex numbers. This paper shows that the suggestion is indeed the case in the sense of precise assignment, by modifying the feedback control by raising frequency.
