| Outline of Final Research Achievements |
For the purpose of construction of the theoretical framework of the delayed feedback control method, we engaged two themes, relaxing the restrictions to the gain in our results in 2011 and the analysis of the case which includes errors in the delay. Although we had not obtained the perfect solution, we could three new results. (1) We prove that Echo type of DF control which is a delayed feedback control with 1 advanced step time is effective. (2) We prove the necessary and sufficient condition of the Floquet multipliers of the periodic solution for DF control to be successful. (3) We prove that the existence of periodic solutions of nonhomogeneous linear systems generated from a periodic evolutionary process.
