Abstarct: In this thesis, synchronization of the special class of chaotic systems by using of hybrid control is studied. Sliding Mode Control (SMC) is one of the easiest method in the design of robust controller, in addition to all the advantages such as fast response, high accuracy and insensitivity to parameters uncertainty it has a major shortage which is called chattering phenomenon. In this thesis, to reduce the chattering of SMC we use the hybrid control scheme. In this scheme, SMC and Linear Quadratic Regulator (LQR) controller are combined by Fuzzy Logic the stability of the proposed method is given by Lyapunov. Efficiency of proposed method is illustrated in comparison to SMC and Fuzzy SMC by applying on the chaotic gyroscopes. The results show the superiority of the proposed method.
