In this paper, we firstly make some qualitative analysis to Lorenz critical chaotic system, and then lead it to the corresponding unstable equilibrium point and periodic orbits in terms of the linear state feedback approach. Then we make a lot of simulations which indicate this method to be feasible. Fractional-order system, as well as Lyapunov exponent, has been used as a powerful tool for the quantitative study of chaotic systems.

For I will fly to thee, Not charioted by Bacchus and his pards, But on the viewless wings of Poesy, Though the dull brain perplexes and retards Already with thee! tender is the night, And haply the Queen-Moon is on her throne, Cluster'd around by all her starry Fays; But here there is no light, Save what from heaven is with the breezes blown Through verdurous glooms and winding mossy ways.

我要飞向你，不用酒神的车辗和他的随从，乘着诗歌无形的翅膀，尽管这混沌的头脑早已跟随你，夜色温柔，而月后正登上她的宝座，周围是她所有的星星仙子，但这处那处都没有光，一些天光被微风吹入幽绿，和青苔的曲径。
