Abstract: This paper addresses the fixed-time observed synchronization of chaotic system. Considering the real situation, different from the research before, this paper assumes that all the state variables of the drive system are unavailable in some periods. Some new fixed-time stability theorems and high-precision estimations of the settling time are presented which improve and generalize the corresponding recent important results. By using the proposed stability theorems, some fixed-time convergence criteria are presented. A simulation analysis is given to show the effectiveness of the presented control strategy.
