Tracking and controlling to reaching of arbitrary signals in uncertain chaotic system is realized by nonlinear feedback control.Proper feedback mode is selected according to the characteristic of system structure， and a nonlinear controller is designed.The sliding mode control theory is applied to prove that the error signal is exponentially stable at zero and all variables in controlled system are bounded.Compared with the control laws in current literature， the controller designed here not only takes the uncertainty of the system into consideration， but also guarantees that all the system states are bounded.The proposed method is a physically feasible tracking control strategy.The results of numerical simulation further proved the feasibility of this method.
